For I am only human, and the convenience of streaming services has most certainly turned my head. All that content at the touch of a button and for a relatively low, sign-up-and-try-and-forget-about-it monthly fee.

The devil is in the detail. Aside from the whole argument for the value of physical media over streaming - which, in the case of vinyl, I'm very much on board with - 4K Blu-ray discs have still clung on in my mind as the superior choice when it comes to performance. For not all 4K pictures, nor all next-gen audio formats, are equal.

See, 4K Blu-ray discs run at up to 128Mbps. This is the amount of data sent to your screen every second. By contrast, streaming services tend to top out at around 17Mbps. And this will drop further depending on the speed of your internet connection and demand on the wider network. So 4K on disc should be better than 4K via your favourite streaming service.

What about sound? It's a closer call but there's still an edge for Ultra HD Blu-ray. Yes, you can get Dolby Atmos pretty much everywhere, but streaming services deliver it in the compressed Dolby Digital+ format while discs generally carry it in full-fat Dolby TrueHD. As for DTS:X, you need to be watching on a disc. And of the two next-gen audio formats, DTS:X is a bit more flexible. It works with standard surround sound set-ups and doesn't require extra overhead speakers the way Atmos generally does. You can also manually adjust sound objects, meaning you can crank up the volume of voices on a soundtrack making it easier to hear dialogue (a common gripe).

Ultimately, my old Blu-ray player should still deliver a better picture and sound performance than the same thing via a streaming service. Hurrah. I knew I should have been buying more 4K Blu-rays. So now, having finally decided to soak up those extra megabits, why was I left disappointed?

Alright, if you don't have the latest TV, you're watching on a smaller screen or you don't have much of a sound system, you may not notice these differences, but for those of us eager to be getting our TV and films "as the director intended", we don't want to miss out on so much as a smidgeon of AV information.

We've been here before of course, when low-quality MP3 downloads and then streams replaced CDs, despite being far inferior sonically. The good news is that we did eventually get lossless and high-resolution audio from streaming services. The quality did catch up with the convenience. And it's fair to say the gap between Netflix and 4K Blu-ray is already much (much) closer than MP3 and CD.

So we could all keep (or start) buying more 4K Blu-rays. I know plenty of people who do, whether for the reasons above or because they love physical media (and steelbooks). But for those who have left discs behind and have no desire to go back, there is hope.

Both Apple TV+ and Disney+ now boast up to 40Mbps and 30Mbps top data speeds respectively, though your experience will depend on your devices and network. Sony's Bravia Core service, meanwhile, offers genuine 4K Blu-ray-baiting data rates but is exclusive to Sony's flagship TVs. Bravia Core does point to the future of streaming, though, and of course the beauty of software is that it can be upgraded and improve over time.

Noticed that I can go up to 5800 on the netflix app (on pc) and only up to 1750 when watching certain movies on chrome. So if you want the best quality, I suggest using the app from the marketplace. ?

This is where the streaming revolution comes in. Smart TVs and streaming devices give access to apps such as Netflix, Prime Video, Disney Plus and more, meaning people can watch millions of hours of movies and TV shows, in up to 4K, for set monthly fees, which ends up being significantly cheaper, and tidier, than buying hundreds of Blu-rays.

So it begs the question: why would people bother with physical media such as 4K Blu-ray anymore? As someone with experience in AV retail and now a tester of TVs, I knew there was a quality difference so I decided to check it out for myself and the results were surprising.

For these tests, I used the Panasonic UB154, a budget 4K Blu-ray player and the Panasonic DP-UB820, a mid-range 4K Blu-ray player connected to the Panasonic MZ1500, a mid-range OLED TV, which was set to Filmmaker or Cinema picture mode, and watched the same movies on both Blu-ray and streaming.

Beginning with John Wick 4, I immediately ran into some trouble. Advertised as 4K on Prime Video, I could not get it to stream anything higher than HD (after some research I discovered I was not alone) so I opted for HD quality vs standard Blu-ray.

Moving on to Godzilla vs Kong, again in 1080p HD on Netflix vs standard Blu-ray, and it was the same story. The Netflix version looked better than I expected, carrying a lot of the vivid, colorful punch on the neon signs in Tokyo that was on the Blu-ray version but again the Blu-ray version showed deeper black levels and more refined details and textures. I was still, however, impressed with how good the streaming version looked.

Finally, I managed to test a 4K Blu-ray vs a 4K stream in the fantastic re-master of Alien, which was on Disney Plus. In both versions, black levels and contrast were superb, capturing the eerie, doom-laden nature of the movie well. Textures were again sharp on both versions. Although there was that little bit more perceived definition in the 4K Blu-ray. Skin tones, for example, looked accurate on both, but more so on the 4K Blu-ray. It is worth noting that the Disney Plus version was in HDR10, whereas the Blu-ray version was in HDR10+, which gave the Blu-ray the perception of a clearer picture.

Whether it was the UB820 or UB154, Blu-ray did indeed have better picture quality overall thanks to 4K upscaling and performance, but the comparison between them and streaming was closer than anticipated.

After being surprised by picture quality comparisons, sound was the next logical test. Running the Panasonic MZ1500 through a Sonos Beam (Gen 2) soundbar, one of the best soundbars at a mid-range price, I tested the same movies again. This time, the difference made itself known.

For Godzilla vs Kong, the story was the same. The roars and shrieks from Kong and Godzilla sliced through the room with more heft when played through the Blu-ray compared to streaming. The crunching blows and shattering of buildings during their climatic fight scene had more direction through the room and just more power altogether. This not to say the Netflix sound was bad, just that the Blu-ray did it better.

When I put both Blu-ray and streaming in as close to the same conditions as possible, I was pleasantly surprised by just how close the picture quality battle was. Both had excellent details and colors that would make any viewer happy, although for the real movie lover, Blu-ray had the upper hand thanks to better contrast levels, despite streaming offered a suitable alternative.

To clarify, a streaming device is a piece of hardware, like a Roku or Apple TV, that streams content to your television. A streaming service is an app, like Netflix or Hulu, that you can watch on your streaming device.

However, most streaming devices do not decode surround sound and instead transcode encoded surround sound signals into a format that can be decoded by a TV, soundbar, home theater receiver, or other external audio systems.

There are many streaming services that offer movies or shows in surround sound. Some of these apps may be built into your smart TV while others require installation on a streaming device. Each streaming service offers different types of surround sound compatibility, including 5.1, 7.1, and Dolby Atmos, which adds audio that comes from above you, rather than in front of or behind you.

Netflix is one of the most popular and well-known apps for watching movies or TV shows from your home theater system. This app offers a huge library of on-demand programming, with thousands of titles in surround sound or compatible with devices or smart TVs.

All titles supporting 5.1 surround or Dolby Atmos have high-quality sound. A Dolby Digital Plus icon or a 5.1 symbol will appear next to the description of any title with 5.1 surround sound if it is available. If a title has Dolby Atmos, a Dolby Atmos icon will display next to the description.
