Don't forget there are limits to how many shades of gray the human eye can distinguish, how many shades that is I don't know but I have a hunch it is less than 2^16 shades (16 bit grayscale)which is 64K shades.
My Noritsu tech (I think the company does research into what the human eye can discern) says that we can see the equivalent of 24 bits per channel colour.
I expect that this number will vary wildly, depending on ones age and a myriad of other factors.
