Linux and Gentoo in particular supports 10 and 12 bits per channel. 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].
