This is "dynamic range" vs. "absolute number of colours". The human
perception varies a lot accoridng to the environment, and, while the human
eye has difficulties with a large number of different colours, it is very
sensible to banding, and different media (film) must support a very large
dynamic range.

Digital effects filters also eat a lot of resolution.
