in a techdoc regarding WCS Gamut mapping strategies I've found that Windows Color System will match the whole grey axis on to each other.
It depends a lot on the details. By "whole grey axis", do you mean the white point to the black point ?
Where does the black point come from ? There are lots of ways of choosing a black point. It might be the darkest point that is achievable in a gamut. It might be the darkest point in the black ink chromatic direction that can be achieved in a gamut (that's what Argyll's profile does for CMYK devices.) It might be the darkest point in the line between the white point and Lab 0,0,0. All these "lines" and "directions" might be in XYZ, L*a*b*, CIECAM02 Jab, or some other colorspace.
Are you referring to "perceptual" intent (or something analogous) ?
(I expect it may be a bit difficult to pin down the answers to these questions from the available WCS documentation !)
