Even the “digital” home video remasters deliberately departed from the theatrical colors to create a specific “aesthetic” to their look.
The 04 and 11SEs, I really don’t know what they we’re going for. Incompetence maybe?
The 1920SEs have gone for a muted and more desaturated look. Empire has a green/blue push introduced, whilst Jedi has a red push making everything look kinda brown. However in these releases there is pretty good shot to shot consistency so you can do a lot with a single color correction to the whole films to improve them.
Check out Jedi Destiny if you’re interested. We’re also working on Empire atm.
