There are evidently utilities that will let you do this, or you can look in the file with a hex editor and find the profile name. Or you can change your Photoshop RGB working space to something that won't match the file, try to open it, and let the Photoshop Profile Mismatch dialog tell you what it is (as long as PS is set to do this on a mismatch.) But if you are doing multiple conversions on a file, be careful you do not fall into the Photoshop Profile-to-Profile conversion trap. You can convert an image from anything to anything within PS, but as far as PS is concerned, its embedded profile is always your RGB working space after you load the file. If you are editing in Adobe RGB, and you convert an image to ColorMatch RGB, the file will be tagged as Adobe RGB if you save it. The tag corresponds to the working space, and it has nothing to do with any conversions you make to the file (at least within RGB spaces--presumably if you convert it to CMYK, it will be tagged with a CMYK space tag.)
