I think this method will be the way to go when doing color corrections of the Blu-ray, as it automates what would be (and was) hours and hours of work trying to rescue these shots using manual color correction. There will still be problems with the Blu-ray that need to be corrected by hand of course, such as R2's dome in the above shot, which is oddly green with purple panels. That's just the nature of the blu-ray, that some shots are missing color channels and gradients and nothing can be done to fix that without pulling in color information from another source.

I agree. I mean, it will still be hours of work. And many, many, many hours of rendering time. But, assuming the references are correct (and Mike Verta will someday post his own collection of every shot which the majority of us here will have some faith in), it takes all the horrible second-guessing (and third, fourth, nth) you have to do when adjusting color manually.
