I worked at a Technicolor facility and spoke with the aforementioned Marc Weilage in 2004.

The story he related was that a few guys went up to San Rafael to color the Star Wars DVD release, but they weren’t at the Ranch’s top facilities. There was mention of card tables, temporary workstations, and other less-than-ideal work conditions. The impression I got was that this was quick and dirty.

Based on the results of the Blu Rays, I highly doubt that much more attention was paid to any kind of reference for that release.
