We would want 10 bit screens because the research indicates that the dynamic range of human vision is around 90 dB or 1:1,000,000,000, which is alarmingly higher than even 1:1,024
According to Pantone, "Researchers estimate that most humans can see around one million different colours". So research says we only need 7 bits.
"Research".. sponsored by corporations, and peer-checked by scientific voting rings. A bunch of incrowd elitists who like to use jargon. Science and politics these days are pretty similar

If all research is wrong, I'm gonna start drinking vinegar and building perpetual motion machines :P
