It depends on what workflow you are after. As Claas outline, you can
certainly create a CLUT sRGB profile that can then include
gamut mapping in its B2A tables by creating a test chart and using
fakeread + colprof.

Right, but a device link using "collink -G ..." will result in a much
higher quality transformation directly from one RGB space to another.
