Re: [Gimp-user] 10-bit display color depth support (30-bit, deep color)

[LKH <lkhgraf protonmail com>]

Yes I have tried GIMP 2.99 on Linux with 30-bit depth enabled as verified with xdpyinfo and xwininfo. It does 
not display in 30-bit as far as I can tell. In fact I have not been able to identify any Linux software that 
will display an image in 30-bit. GIMP also does not display in 30-bit on macOS and Windows, but some other 
software does.

Conceptually this is definitely not something that would just work without the developers going to some 
lengths to implement it, completely regardless of internal representation of the image. It doesn't matter 
that internally the image might be 16 or 32 bits per channel, displaying it in deep color is another matter.
