10-bit color on OSX El Captain

The first thing.. okay the second thing I noticed when looking at a couple Retina iMac was the large amount of banding in gradients.
Like this one:

It seems that Apple was applying a correction profile on only 8-bit - and quite a bit of it, which on this very large and sharp panel created simply banding galore.

10-bit, even for apps that support only 8-bit per channel (24-bit colors) should at least fix the calibration banding issue, if all is as it should be.
