Here is the “final” version using my method and not making it so tight. It still corrects the color, but doesn’t clip as much.

And here is the same but further adjusted using the channel mixer to try to get the sky to be less green in the Bluray1 version: http://www.framecompare.com/image-compare/screenshotcomparison/91MNNN8U

Edit: I just started playing with the Curves option and noticed I can use my same method because there are sliders, but there is a “show clipping” checkbox. This is really cool because I can adjust to the edge of the ramp up just before clipping and it still works sort of automatically. After doing the curves, I can go into levels and adjust the middle slider to get the gamma without clipping and then use the channel mixer to make subtle tweaks from there. Very cool!

Edit 2: just for fun I tried Auto Color and it ended up looking almost identical to the method I mentioned in my first Edit. The problem with Auto Color is it can’t be reliably applied the same way to each frame in a sequence of frames from the same scene.
