Okay, after much comparing using screencap comparisons, the newer settings do go a little too far in trying to remove the blue shine that me and towne32 have noticed with the older settings, so I've gone back to the older settings but i've found another far more subtle way to remove that blue shine but keeps the rest of the colours pretty much intact. I'm 100% satisfied now with how it looks and have finalised the Retro, Classic and Technicolor settings for all three films.
If anybody wants to see how a certain part will look from Star Wars, Empire Strikes Back or Return of the Jedi with one of the three settings, let me know the timecode from the blu-ray and i'll put up a 1 minute regraded clip from that part so you can see how it'll look on these Semi-Specialised editions.
