can’t the scan be color corrected to match the original color timing?
Not really. The scanned print had a misaligned dye channel, and an already encoded 1080p mpeg2 bd25 is the best quality anyone has of that scan. Instead of investing thousands of hours in manual clean-up my suggestion is to start fresh from a better source. The end result will be much, much better. Getting a 16mm print scanned in 2K full aperture DPX would be much higher quality than the 35mm HD Telecine transfer (and also better than the existing 16mm scan as well, obviously).
