The frame is from Dr Dre’s thread there : https://originaltrilogy.com/topic/Star-Wars-1977-Technicolor-IB-print-color-references-matched-to-print/id/55404. So the scan is accurate to the print
If I well understand you, a single correction could do the job, and it would be visible in the brightest shots only.
EDIT : For the sunset, the same correction is hardier noticeable http://www.framecompare.com/image-compare/screenshotcomparison/FJEFNNNU
