| captain carot said: 4K or UltraHD is about high dynamic range, deep colour etc. as well. Especially high dynamic range is interesting here, deep colour is also though. Basically the most interesting things about 4K don't have much to do with resolution at all.

I would say deep colour is more important for movies. Cinemas don't have and can't show HDR effects. Looking at 4K blu-ray reviews, the ones that are received best are because of deep colour, those with enhanced HDR effects tend to be less favorable. It is still early days, every release is different. Some still have issues with black level, a lot are upscaled from the 2K source. The Revenant seems to come out best, reference quality material, doesn't support HDR.
Ofcourse 4K tvs are currently rated on how well they can display HDR material. I assume that implies also being able to show 10 bit color as intended.
