The YUV layers are 16 bits per pixel, but pairs of horizontal pixels share the same chroma giving you effectively 24 bits per pixel.
i'm confused...do you mean that there's 16 bits for luma and 8+8 for chroma? Cause if there's 16 for everything, then wouldn't having a lower horiz resolution for chroma mean (effectively) less than 16 bits per pixel?
There are 24 bits that go into the color of each pixel. Some of those bits are not independent between paired pixels. I'm sure there are a number of ways of interpreting "effective" bits per pixel that I don't want to get into, but if there's no way of getting more than 5/6 bits per channel out then you're certainly not going to be displaying more colors than RGB.
