When people refer to ProPhoto RGB as a wide-gamut space, one tends to think
that since it's purported to be "larger than AdobeRGB", it must *encompass*
it all the way around. That assumption is incorrect: there is a relatively
small but noticeable range of cyans and purples in AdobeRGB that falls
outside the gamut of ProPhoto RGB.
Marco, that's an artifact of some but not all 3D graphers. Adobe RGB
is D65, ProPhoto is D50, and ColorThink, for example, shows some
Adobe RGB (and even some sRGB) colors as being outside ProPhoto
because the neutral axis is skewed.
In fact, ProPhoto does encompass Adobe RGB. I'm about to board a
plane for foreign parts so I probably won't be able to discuss this
at length, but check with reliable sources (Steve Upton, for
example). I'm sure they'll tell you the same thing.
