Frankly even 4K sounds low for a movie theater sized screen, personally I would consider 8K to be about the bare minimum to be called reasonable and given the high dollar movie industry I'm surprised they aren't using something really exotic.

4K is more than enough for a movie screen, more or less independent of size. Our eyes have finite resolution, and typical 20/20 eyesight can’t resolve more than about 5K when the screen is filling our central field of view. (See attached image from https://www.4kshooters.net/2014/08/11/4k-resolution-and-the-human-eye/ )
Add in the fact that we don’t need as much resolution for moving pictures as for still ones, and it becomes a fool’s errand to strive for more — on the output. It’s more data to distribute, and less efficient to display, since each subpixel needs borders and internal structures, regardless of how large it is, so lower resolutions yield more light transmission.
On the recording side, more resolution makes sense, since it gives more flexibility to crop, etc. in post.

90deg must be lover optimal resolution than 11K. gausian curve
NiHaoMike:
A little detail often missed is that while displays have the same resolution for color and brightness, most video formats in common use (at least for content distribution) halve the color resolution. Thus, on a 1080p display, 4K downscaled to 1080p looks a little better than most native 1080p content.

Time to just give up and admit it; apart from convenience, film is, and was BETTER, always, in ALL respects.

For stills, the only technical advantage of digital over film is that high-speed film is now hard to find, and high-ASA digital works reasonably well compared with 35 mm film.
However, you will take my 4x5 and 8x10 inch film cameras from my cold, dead hands.
