When you bought your new TV, did you buy an LCD or a Plasma? And if so, why did you buy it? I believe you bought the plasma because colours are more vivid and blacks are better. I think you'll see a similar impact with deep colour with support for "up to" 36-bit colour. The human eye is analogue and can therefore process an infinite colour pallete. Really speaking then, the question isn't how many colours can the human eye detect, it's how many colours can the brain detect. That, ultimately, depends on the individual. In this report, the reporter says he was unable to see any difference above 30-bit colour. While that may be the case for him, what's to say he isn't colour blind? The same can be said about the human ear. Can someone with imperfect hearing hear the noises at the same frequencies as someone with perfect, or near perfect hearing? No, of course it doesn't, but that doesn't mean there isn't sound (that people can hear) at the frequencies which the person with imperfect hearing cannot hear.
