But in order for this to work you need to have support from all chain, both hardware and software: application -> de/wm or rendering stack (gtk/qt) -> xorg (supports) -> video driver (see below) -> video card -> cable(! ) -> monitor You have not told us what is your video card, but at least Intel[1] and nVidia[2] products support 10/12 bits in Linux. Definitely not all application support deep colour (10/12 bpc), but most multimedia oriented do: gimp, ffmpeg, mplayer, mpv... You may encounter some problems with GTK apps, though the proof links I found[3,4] are quite old and situation may have improved. Also take a note that 10 bpc imposes some limitations on the screen resolution depending on your connectivity[5].
