Yes, I think that removing the pink tint will reveal the underlying color grading, specific just for this edition; of course, regrading it using a 1997 SE 35mm as color reference will be great but, if this scan is available, will be a way better way as source for a project.

I think that, with some patience and skill, would be not that hard to find a way to remove this pink tint, using some proper reference images.

I must add this: a direct comparison with the '04 reveals that in many shots where '97 has a strong pink tint - like in the Orange Tantive corridors - '04 is better, while in some others - like inside shots of the Death Star - '97 is better… maybe a “mixed” color grading could be an idea for another project! 😄
