A decade maybe.

Once eye tracking catches on the render requirement will vastly diminish with foveated rendering, meaning 8K 240 fps rendering could be as cheap as 1080p 120 fps. The trick, you only see sharp in 5.2 degrees of your visual field.

8K screens already exist, not at 5.7" yet but that won't be long.

It won't be long before VR games look better than games on TV

You know that's really not too long.  The great news is in 10 years we should have the average game made in a resolution of FPS that's at the limit of what our eyes can see.  So they're will be no need for increased performance meaning developers can focusing on improving other aspects of games.  Exciting times ahead. 

That's not the limit yet. Human vision covers almost 170 degree horizontally per eye (210 degrees wide combined) and 150 degrees vertically. The human eye can spot differences upto 200 pixels per degree, which comes to a screen of 34,000 x 30,000 per eye.
fps limit is harder to tell yet tests have shown that flashing pictures for 1/300th sec can still be identified, and flashes at upto 1/1000th of a second.
Resolution is only one part, humans can see a lot more colors and contrast than screens can provide nowadays.
Plus 3D vision is a lot more sophicticated than how sterographic displays work.

There is obviously an end point to refining displays that look as good as the real thing. Or maybe not, feeling the warmth of the sun shining through the window, wouldn't even know how to reproduce that.

Developers can already focus on improving other aspects, yet graphics sell best. There are still plenty performance sinks to overcome, real time raytracing, realistic skin, hair, clothes, water interaction. The graphics race won't finish any time soon.
