Wouldn't applying a LUT shrink the gamut of the display? In that case
first you use the monitor calibration which shrinks the gamut and then
you use the shrunk gamut to create a profile/LUT that further shrinks
the gamut. Excuse me if I'm not making sense, because I'm fairly new
to colour management.
