About screenshot specifications for Apple App Store

[P5music]

I asked this question on the Apple developer forum but I got no answers.

Maybe some developers here, that have released on the Apple App Store, have the answer or some  suggestions.

I am going to test my app on a real iOS device to check if it can work.

In the meanwhile, I am also creating the images for my app product page in the App Store.
I see that there are screenshot specifications to follow, that seem to be reasonable. Indeed they have the resolution of the screen of the iOS devices.

I would like to understand what scenarios are possible:
1- artwork images has to be created that have the right size for the devices displaying them on their App Store (target screen), and they can also contain an area depicting a device running my app (for example, rotated and surrounded by a nice background and some text)
2- a simple screenshot of the app

Many tutorials show that kind of images of scenario 1.

But the "screenshot" size requirements clearly refer to the device screen size, for a screenshot.

On Android, phone, tablet 7", tablet 10" images are requested, and on the target device the corresponding ones are displayed first but also the other ones will then be displayed.

Every response is appreciated.
Thanks
