No, there isn't anything special about the Fiery Color Profile Software.
ICC profiles are completely non-propietary. If they weren't, they'd be useless. So you can use any profile made by any profile-making software to define color for any device.
The trick, though, is that unfortunately what that also means is that just because an ICC profile is a valid profile, that doesn't mean it's a good profile.
What an ICC profile is is a characterization of a device producing color with primaries in a certain state. And while it's not too hard to get a machine to run some patches and then to read them and get a result, creating the proper machine state before you do can be something more of a challenge. Also, there are many, many ICC profile-making engines out there. A couple of them are excellent, a small handful are very good, a goodly number are mediocre, and there are more than a few that suck.
Personally, I have a fair bit of experience with the Fiery engine, and I'd rate it in the handful-of-very-good group, although not quite one of the best. The Creo I'm unfamiliar with. You'd assume by the name Creo that they'd know what they're doing...but then again, in this business, assumption
can get you into trouble.
Good luck,
