I think you are only illustrating that 16.4m colours far exceeds the discrimination of 
human vision, and that 8 bits should be enough for anything we intend looking at. You 
can, though, often see differences of ~3-5L if there is a suitable reference, though 
it depends on the colour and luminance.
