Yes, Photoshop 5 would only allow similified matrix spaces to be used as RGB
workingspaces, but Photoshop 6 will allow much larger, more complex 3d
look-up table profiles to be used for viewing RGB files as well. Their are
various theories about the potential value of this as specialized, exacting
working spaces, and concerns about the ability to display such spaces on the
monitor in a manner that will allow for effective visual editing; but
certainly this ability is excellent for viewing images in RGB printer spaces,
and other such uses, even if you don't define special workingspaces with it.
