I think you know my view already. I'm in favor of the latter. :)

Had a similar problem in THX where the white void is yellow and red/pink at the same time, in RGB colorspace I believe it would've been an easy match but in YUV colorspace it's nearly impossible to correct. How the hell do you guys do it.

Why don't you convert to RGB to perform your color correction and then back for encoding? The quality loss is minor, in my opinion, and more than worth it.

EDIT: Your latest sample looks good to me.
