There are exceptions, such as people gifted with abnormally good eyes, but for the vast majority of people those are the limitations. It's not so much about having better quality material on the screen as much as your eyes can't register the extra resolution. That's why the jump in picture quality from SD to HD was so huge and the jump from HD to UHD isn't when UHD is 2160p. Think about it. If 360p to 720p brings on such a huge jump in picture quality why doesn't 1080p to 2160p bring in a bigger one?. Your eyes can pick up 360p to 720p at normal viewing distances on, for this argument, a 40". At the same time, your eyes can't pick up the jump from 720p (or 1080p) to 2160p at the same distance.
Let me use a practical example, to see if I can explain what I am talking about.
let's say you are playing a game with first person perspective, and you come to a rope bridge like this one:
however let's say that bridge is so long, it fades off into the distance. the last several board you can see before you can't see anymore, will be about 1 pixel wide. If in real life, you then tilt your head, the end of the bridge would look the same. However on a TV, the end of the bridge will start to moire, like this:
This effect you will see at any distance in a room. As the resolution of your TV approaches infinity, this effect approaches zero. The higher resolution your TV, the less this will happen. Game developers get past it by using anti aliasing, but that degrades the over all image.
This is why while playing a game, if you had a 10K monitor, at 10 feet away, it would be better then a 4K tv, and that would be better then 1080p (provided the game had variable AA at those resolutions).
Once game manufactured no longer care about AA, and not using it does not produce the above effect, we have reached max resolution. We are far away from that point at the moment however.
For watching movies, I agree with you, as this effect almost never happens. But this is a game thread :)
