Have to remember however that this is for video content. Video game content is obviously going to be much different because Pro and XBox One X also push higher texture detail, whereas most, if not quite a bit of video content, is still shot in 720p-1080p and upscaled. You can completely tell the difference between something like Planet Earth 2 (Shot in 4k) compared to another program (Disc) where it was upscaled or "Enhanced". Which is really the crux of the problem still today.
Distant Viewer has always been dependent on what content is being shown and what source, and that is such a toss up right now that those numbers aren't entirely accurate. Video games however, with higher textures, AA, and higher resolution whether dynamic, checkerboard, or native, you will see a bigger difference.
