[argyllcms] Perceptual intent for colour managed display

Hello,

I would like to make sure my understanding of the following matter is
correct, sorry if it is obvious for all:

The perceptual (and saturation, too) intent requires that both source
and target gamuts are known when profiles are created and this intent is
supported only by LUT profiles (not the shaper/matrix ones).

Which implicates that if one wants to use the perceptual intent for
displaying images on the monitor, one must create several monitor
profiles for images in working spaces bigger then the monitor gamut
(AdobeRGB, ProPhotoRGB, etc.) and possibly also for the printer profile
for soft-proofing.

These monitor profiles would behave the same way for the colorimetric
intents, but will provide different results for the gamut mapping
intents (perceptual, saturation).

Is this true?
