Does this help. The Refracted Light Blog has a thread on
Imaginary and Impossible Colors, and in there, they have:
Here are the most commonly used color systems:
sRGB: 35% of entire gamut
ColorMatch RGB: a bit larger than sRGB, slightly different
Adobe RGB: 50.6%
Wide-Gamut RGB: 77.6%
CMYK: smaller than sRGB, but not complete overlap.
ProPhoto RGB: most of the visible color gamut, 13% of the colors
are imaginary or impossible.
L*a*b colorspace: 100% of visible colors, with lots of impossible
Anyway, there is more there to read. It probably doesn't anwer
all questions, but it might give you ideas as to what else to look
