For this to all work, it's more than just the monitor vendors. The OS and applications need to be able to fully work in a 'high bit' environment. Maybe the chicken and egg syndrome but it's more than just hardware.

Quoting again from Karl Lang's famous Betterlight post:
1) A wide gamut LCD display is not a good thing for most (95%) of high
end users. The data that leaves your graphic card and travels over the
DVI cable is 8 bit per component. You can't change this. The OS, ICC
CMMs, the graphic card, the DVI spec, and Photoshop will all have to be
upgraded before this will change and that's going to take a while. What
does this mean to you? It means that when you send RGB data to a wide
gamut display the colorimetric distance between any two colors is much
larger. As an example, lets say you have two adjacent color patches one
is 230,240,200 and the patch next to it is 230,241,200. On a standard
LCD or CRT those two colors may be around .8 Delta E apart. On an Adobe
RGB display those colors might be 2 Delta E apart on an ECI RGB display
this could be as high as 4 delta E.
It's very nice to be able to display all kinds of saturated colors you
may never use in your photographs, however if the smallest visible
adjustment you can make to a skin tone is 4 delta E you will become
very frustrated very quickly.
2) More bits in the display does not fix this problem. 10 bit LUTs, 14
Bit 3D LUTs, 10 bit column drivers, time-domain bits, none of these
technologies will solve problem 1. Until the path from photoshop to the
pixel is at least 10 bits the whole way, I advise sticking to a display
with something close to ColorMatch or sRGB.
