Just as a reference this is a PEW Champagne:
A "Pink" eyed white's eyes are not really a pink color, more bright red. A Red eyed rat has dark red eyes, kinda maroon.

Also the rat in the picture at http://fancyrats.pbworks.com/w/page/8715181/Champagne (correct me if I'm wrong) has pink eyes.
Hard to tell from your pics but your suspected Champ look like it has pink eyes to me.
