Yes, I still have a copy of v2.1… I remember the Ben Kenobi desert scenes were adjusted because they had been a little blown out to look like the IB Tech print from that theater screening and then Harmy sort of dialed that back to look less so. That’s around the time the whole '70s look was coming into the presentation…
That gives you an idea of what direction the colors were going toward at that time, but many changes to the overall palette and timing have come into play since.
