But it's not from resolution alone. Otherwise, wouldn't high-quality super sharply focused film movies have provided that "pop"? I see nothing inherently "flat" about lower resolution per se.
There are really nothing to compare with today in terms of resolution. 35mm film is about 3.5K at best, but can be scanned at 4K or preferably 6K and down-sampled an can yield a Ok 4K image on a 4K projector.
Most digital shot films are still finished at 2K and are said to equal 35mm film projection.
Film shot digitally on a camera with higher than 4K resolution and down-sampled to 4K has been projected digital in side-by-side tests with 70mm 5perf and Imax 70mm 15perf and match the 70mm and the 16:9 portion of the Imax screen.
But this is big screens and long seating distances, and the PPI is really very very much lower than the screen of a mobile phone or "retina display".
Go from 4K/ 8 megapixel up to 8K/ 33 megapixel on a smaller screen and everything changes.
The only way I know of today to test high resolution to get some kind of idea of the effect of high PPI is if you have some good lit fine grained positive 35mm film (twice the framesize of 35mm cine film) and put it in one of those small plastic slide viewers you hold up to one eye. Do it in good daylight.
There you will see the almost 3D depth like image. But because you use one eye and a 2D image, it will look a little like those paper cut out figures that we see in today's badly converted 3D films that where shot in 2D.
Apple iPhone 4 is 329.65 PPI.
50" HD TV is 44 PPI.
85" 8K TV is 103 PPI.
A 50 feet wide cinema screen at 2K is 3.15 PPI.
A 50 feet wide cinema screen at 8K is about 12 PPI.
Remember that a camera with higher resolution will pick up more details (finer texture) to be shown from a high resolution projector on a cinema screen almost regardless to seating distance of a normal cinema. 50 feet wide cinema screen is not very wide. The really large screen are 60-70 feet wide.
