I have seen that there is a good ammount of versions of the original unaltered trilogy, and i am a bit confused about which is the best option to watch them.
If i understood well, 4Kxx are the more accurate to the original, but i also read that Blu Ray source (that was used in Despecialized) are from the original camera negative… So what is the difference between that source and the one used for 4kxx?

I have also noticed that the epic force ghosts scene in ROTJ looks different in every version.
Check this screenshots:

From Harmy Despecialized v2.5 (newest version), clearly looks more “blue”. Why?

From 97 Special Edition :Again there is a color change? Now looking more “grey”.

Which of this is the more similar to the way it was shown in ´83 cinema?
