to be technically correct, matrix profiles don't do any gamut mapping, and any clipping is done by the CMM and is likely to be simplistic, per component clipping.

Note that cLUT type profiles will at least clip to the perceptually closest in-gamut color.

One is the use of "wrong Von-Kries" chromatic adaptation in adapting white points between D65 and D50.

The other is gamut mapping or clipping in L*a*b* space, since perceptually constant hue lines have quite a curve on them near blue.

This I'm aware of and have bumped into before.

be warned than some systems/programs expect display profiles to be matrix based, and choke on cLUT profiles.
