If you see no difference when using this, then it could be because your
own screen is already 6bpc. This is the case for a lot of LCDs, both old
and modern. 8bpc tends to be the norm on IPS, though. 10bpc is the next
step, but for now it's only used internally in video codecs for more
efficient compression with lower quality loss. I seem to recall that in
most *nix systems such as Linux it's possible to have 10bpc already with
NVIDIA, but it causes compatibility issues with a lot of programs.
