I'd say it was rather stupid doing the color correction BEFORE having Lowry clean up and restore the image. If they did it the other way around, they could always go back to the original color (on the cleaned-up master), and make a new color-correction from there. Now, once they want to change the color-timing considerably (and most importantly fix the crushed blacks), Lowry would have to re-do their clean-up as well, I guess.
Short-sighted and incompetent...
