Here is a good example i just wanted to help the issue with distance.
We all can agree it just depends.
"However, while we’d agree that you get the most impact from 4K if you sit close to it, we reject the notion that you get no benefit at all from more distant viewing positions. You still perceive more depth, colours still look more smoothly rendered, and objects within the picture still look more solid and three-dimensional. "
Remember these days. Going from 720 to 1080p.
"How Important is the Resolution of my HDTV?
The simple answer is that the native resolution of a particular HD screen isn't that important.
Whilst there are some circumstances where you will be able to see a difference between a 1080p and a 720/768 screen, in the real world this won't be a huge issue for most people.
Therefore it is not crucial that you buy a TV with a 1080p resolution."
"The factors that make a difference when it comes to the native resolution of your screen are:
The size of the screen
The distance you sit from the screen
The resolution of your source images
The quality of the TVs processing
To get the full benefit from a 1080p native resolution screen you need to be watching a true 1080p source, and then you need to be sitting relatively close to the screen - or you need to have a very large screen - or both!"

Again i just want to point out how this is all easily the weirdest thing. History repeats itself.
I just got a kick out of how it mirrors the 720p to 1080p jump.
Now we see the exact same thing going 1080p to 4k.
