Weird output profile behaviour

I have an CMYK output profile (that I didn't create) that I believe is acting odd.

The perceptual rendering intent produces *much* higher saturation that the relative colorimetric intent. I know that profiling apps are free to build perceptual rendering as they want, but my experience with other profiles has been that the perceptual intent produces lower saturation that R.C. I get far better colour matching using the perceptual intent, while rel. col. seems to produce suspiciously blue results.

As well, the relative colorimetric intent produces *identical* results to absolute colorimetric. So if I convert an arbitray L*a*b* colour to CMYK using this profile, I end up with the exact same device values from either intent.

Does this seem weird and/or wrong? Or is there something I'm missing? It's almost like the absolute rel. tables ended up as well in the rel. col. tables, and the rel. col tables ended up in the perceptual slot. Is this possible?

Thanks,

Matt Larmour
