I think the detail-differences are just caused by the two images not being the same frames in the movie. As you can see, 3PO isn't as close to the camera as in the upper image, and so I guess reflection on R2's blue parts occures in this later (or earlier) frame.
But it's true, the images are still a little over-saturated. This is especially visible on these screenshots:
They look kinda sunburned... but with a little less saturation your color-correction looks just great.
