The Photoshop ROMM-RGB profile is an ICC V4 profile. It has the real
ROMM-RGB Black Point defined in the I3A Specification. The ROMM-RGB
Device Black Point is identical to the ICC V4 Perceptual Black Point. So
the different Rendering Intent tags in the ROMM-RGB Profile are
identical (they point to the same data in the profile).
The ProPhoto profile is a V2 Profile with a non-realistic Zero Black
Point.

I don't know which specific profiles you're looking at - but ProPhoto
really is ROMM with a more user friendly name. And ROMM is normally
just a matrix/TRC profile (that was part of their design goals), so I
don't know how it could have all 3 rendering intents.
