Correct is a very subjective term, isn't it. Like truth. I guess to summarize what I'm aiming for in fewer words, it is to find a color correction that most closely matches the props, available photos, behind the scenes special features, etc. What I'm not after is matching any particular theatrical presentation. Though what I've done so far brings the Bluray very close to the technicolor prints.
And to aid in getting the highest quality I have finally ordered the PAL dvds. While for most shots the Bluray is unbeatable in clarity, for the shots that have changed and the special features (mainly the Eps 1-3 deleted scenes), I'm hoping the Pal version holds some additional data. An extra 96 lines of data that will make my upscale to 720p less noticable. I understand that doesn't help with the GOUT, but just in case...
