I do see the clipped point being discussed by using ColorThink. Plot a 3D
graph using AdobeRGB(98) in color and "pslabpcs.pf" (Adobe Photoshop CIELAB)
in white, and you'll see a very slight clip at the green point of RGB98. You
may have to rotate a couple times to make it out. There is an odd curve on
the Blue-Green axis of that Lab PCS that causes this. Perhaps someone more
technical than I am can fill in the reasoning behind that curve... I tend to
be more interested in the visual results than the scientific... except in
clipping cases like this.
