DCamProf can make a pure matrix profile (with shaper curves if a transfer function is provided via the -t parameter), and a LUT profile with either camera RGB to XYZ conversion or camera RGB to Lab.

DCamProf can make an RGB to XYZ or an RGB to Lab LUT, the latter is the default. Currently the XYZ LUT uses the forward matrix directly which means that extreme value handling is not as good as the Lab LUT, so I recommend using the default Lab LUT.
