Polymorph or Glamor?

In several stories a character is changed into a beast of some form. Usually a girl with 'some learning' in the arts is able to see the person as they really are/were. Does this mean it isn't a real polymorph, that it is just a glamor spell creating an illusion? Jinns favor Illusions spells to wreak havoc among humans.

Coming full circle, the first incarnation of Arabian Adventures was to be built with D6, MUNF talked me into using GURPS. Now AntiPaladfin Games has a core D6 system good to go.
