gimp has 2 use cases
1) monitor proofing

yet it only has RGB and CMYK choices for working spaces
I don't know if Photoshop or other software has a CIE colorimetric
choice for working space, but in order to measure and track color it
would be a lot easier to have one
I know there are issues like gamut differences and rendering intents
but if you want to measure the colorimetry of the monitor or proof and
match it to the print, you need to start with CIE, not RGB or CMYK,
ideally CIECAM but ICC has not gone there yet as far as I know
The gimp bug report and feature request list is he
https://bugzilla.gnome.org/buglist.c...t%3A%22GIMP%22
did you say before that gimp's CMM was 8bit?
8bit encompasses the visual range of colors, but processing, to meet
Nyquist would be 16bit or higher
I used to make color profiles and know that few have precision of 1 delta E*
I also know there is little difference between good enough color and
perfect color, and that some things are better off left to editing than
specification
