The fundamental assumption is that the gamut of the proofing device is larger
than the gamut of the device being emulated. As soon as this is not true,
even for a small area such as the highly saturated yellows under discussion,
then the only remaining questions are how the gamut reduction will be mapped,
and whether a given image will contain any colors in this remapped area.
Whether the result is most satisfying with Hue, or Saturation, or Brightness,
or two of the three adjusted (or else some related set of triplets), depends
on personal expectation, and on the color that is out of gamut. What looks
like an ideal remapping of yellows will not necessarily satisfy you if the
gamut clipped area is blue!
