Mrak0020 I consider that going from 6-8 bit using dithering, you have
16,777,216 - 262,144 = 16,515,072 colors to simulate.
But with 8-10 bit, you have
1,073,741,824 - 16,777,216 = 1,056,964,608 colors to simulate.
That said, my hypothesis: In order to simulate that many more colors for 8 bit panels, it could be much more noticable and bothersome if someone were sensitive to it. (possibly a lot more happening on the display at one time)
