As a public service, I am providing a key to the rather infuriatingly uninformative names that Canon has given its ICC profiles.
MP = Matte Photo Paper
PR = Photo Paper Pro
SP = Photo Paper Plus Glossy
GL = Photo Paper Plus Glossy II
SG = Photo Paper Plus Semi-Gloss
Numbers appended to the name, e.g. Canon Pro9000 PR1 or Canon Pro9000 GL3, refer to the print quality, with 1 the highest quality.
Hope this helps.
