Looks so clean after your processing. What did you use to achieve such an outstanding result? One of your magic filters? :D
Probably nothing new but I noted a very similar color grading between the THX-PAL and a promotional still I found.

Still: http://www.moviestillsdb.com/movies/star-wars-i76759/6fbb6191
I'm not saying either of them is color accurate, but I wonder if teal indeed was to be so prominent in that shot in the theatrical version. Maybe the THX-PAL is indeed closer to the original.
