Her eyes are probably different because she is a different kind of shape shifter (exp. Kira and Kanima) and as far as we know eye color is only relevant to werewolves. As for Derek it's most likely has nothing to do with paige because if it did it wouldn't have changed or have taken [insert however many years] for it to change back. If i had to guess I'd say it's probably a side effect of the whatever mystical crazy aging thing Kate did to him. Jeff implied in the after show that Kate did something that will have a big effect on Derek and that he will be facing things that no one else has experienced before (at least these characters which i assume included Deaton and Peter) this season. So I don't think we'll be getting such as straight up answer as Nemeton or Paige.

excuse my rant xD

Yep. That's the same thing I said.
