16.7M colours requires 24-bit (8 for each of R,G,B). That's only in video RAM though. Older LCD panels used dithered 18-bit.

Either way, that 16.7M colours may not be able to represent all of the colours visible to the human eye, and the human eye may not be able to distinguish between some of those 16.7M colours.

You have the gamut that the eye can see and the gamut that the computer can represent and the gamut that the device can render. They only overlap in a subset of the three colour spaces.
