Here’s a full mockup of the Ach-To sequence, featuring a regrade by NeverArGreat:

I agree with everyone else that the nighttime and morning regrades look fantastic. Not sold on the evening, though.
Also, I find it somewhat hard to believe that Rey and Luke would be talking ALL night long. Of course, Ahch-To could have a shorter day/night cycle if we wanted to. But the impression for the average viewer is that she was there for about 10 hours. Meh.
Is it possible that when she is burning the Falcon it is night? That would not only make the timing make more sense, but also remove the evening regrade that doesn’t look as good.
The issue is that there are quite a few shots with a bright sky directly behind/through Rey and Luke. I masked those out and darkened them for an evening look, but I don’t know if replacing them with night would work at all, and if it did it might just look obviously day for night. It would certainly be harder than masking the door and window of the hut.
