You are misplacing your disagreement. We don't know specifically what went down when color correcting happened. For all we know they matched the theatrical print and then George would come in and say, hey make this scene this way, change this sequence that way.
At this point, all that doesn't matter, the color changes have been released twice, they are no longer errors made by the color blind, they are definitive deliberate creative decisions, that's the way George Lucas and Lucasfilm want these films to look.
It's up to the general public to now take what's been provided and change it, or the public can stick with older versions. Everyone makes the call, you decided to buy the new set, and watch Harmy's old version.
