I’m curious to see it. If it was me, I’d grab a much smaller number of screenshots as a quick litmus test - maybe something from daytime Ahch-To, the Resistance ship, Snoke’s throne room, rainy nighttime Ahch-To, and Crait. Those are broadly the largest differences in colour and lighting across the film.
You make a good point there. I tend to get carried away when I’m taking screencaps, so I end up with too many of them. I’ll see if I can ease up on the number (that, or get carried away again).
