Yes, this seems to be a rule of thumb mentioned in some literature.
Some of the literature recommends doing gamut clipping in a manner that weighs the luminance errors twice as highly as hue and saturation.
Unfortunately, I have not allowed for such a weighting factor in the clipping code. It might be possible to add, but it would be
some little work, as it would essentially have to be done by adding a value scaling factor to the rspl code (since the internals is too tightly tied to the 3D/4D geometry.)
It might be worhth a try ...
