I've finally managed to find the freaking video online, but since it's Windows Media, I can't take screencaps. Here's the link to it, though:

Inspecting it more closely, I have to say that Disney Duster is right. Cinderella is more blonde, now, and shots where her gown was silver now look (a very pale) blue, though it still looks blatantly silver when you see her transforming. I don't know why I didn't notice this on TV. Perhaps I was too giddy then. Oh, and about the magic sparkles from the transformation shot, I don't think anything has actually been erased accidentally. I think what happened was that we're all so used to the softer transfers that in those, the sparkles blended into each other causing what looked like solid streaks. Now that we're seeing this razor sharp, we're able to see each individual sparkle, thus the streaks around her don't look as solid. Still, I'm not worried. I fully trust Disney with these restorations. As I said earlier, they always refer to the original, untouched animation cels. With that in mind, it seems Cinderella has always been more of a strawberry blonde than a reddish brunette, and I still think her gown is silver, it's just not as blooming as it used to be because the color's been perfected. All in all, it looks to be a fabulous restoration.
