All these screencaps ... My favorite starship ...
I wonder if those color corrections were done initially for the DE, before the editing and new effects were added?
Could it be possible that print was rejected because the color timing was designed with NTSC color restrictions in mind, and would not have been suitable for the Blu-Ray?
Speculation on my part. Well, the Blu is almost certainly the original theatrical release, unmodified.
If they simply played back a working DVD or projected the movie for the commentary, and then the blu-ray encoding was done later or in parallel, it stands to reason this would happen.
