I just used the Apple Care on my never yet carried teal Sabrina. There was a tiny bit of color transfer onto the white cloth, but it was really a very small amount- less than you would see wiping your face with a napkin when you are wearing makeup. It really did seem to make the bag look better. There was a little scuff near the bottom that probably nobody would have ever noticed but me, but it was driving me nuts. Now I can't see it at all

I haven't done the spray yet, but that's the next step.
