Hey Peter,
Yep, it probably does download the most optimal resolution. However, some of wallpapers are simply not available in high resolutions. Out of 34 wallpapers that I have changed with "I'm feeling lucky", 18 of them are in appropriate resolution, and others are in lower resolution and feel pixelated.
Here is the listing from "~Library/Containers/com.commanigy.Wallpapery/Data/Library/Caches/com.commanigy.Wallpapery/0x0/" ordered by screen resolution:

Don't get me wrong. 18 out of 34 is pretty good coverage for such high resolution. However, it would be great if I could ignore these lower res wallpapers from being downloaded altogether, so that I don't have to keep clicking "I'm feeling lucky" until I get the wallpaper that satisfies my resolution.
thanks
