The picture below is found by Google Image search. On Windows, Nvidia settings show 10-bit colour depth for my monitor, but on Linux (installed the latest proprietary driver), Nvidia settings shows only up to 8bpc. My question is, does Nvidia + Linux support 10bpc in the first place? I mean, it would be pointless to try to figure out how to enable 10bpc, if it is not supported on Linux in the first place.

10bpc depends upon your monitor and card. Assuming both can render 10bpc...
- Confirm current current bpc by entering command: xwininfo -root | grep Depth
- Create xorg.conf file by command: sudo nvidia-xconfig
- Open the xorg.conf file by command: sudo gedit /etc/X11/xorg.conf
- Scroll down to where you see the number '24' in the screen section. Change all entries to '30'.
- save. reboot.
- Confirm by command: xwininfo -root | grep Depth
Caveats:
- Only very few number of apps can render 10 bpc; the vast majority render 8; so you will see no improvements. Example: viewnoir cannot, and gives a black screen; but the default image viewer can, and shows the image. At 10 bpc, wallpapers do not appear on home screen: the screen is solid black.
