If true, a mistake. At what point do you notice it’s not there? Like what part of the movie?
Hard to say. I can’t exactly remember the original look of the Blu-ray, but I did wonder why Exegol was looking very blue in the end than gray. I think it’s when Rey arrives in the X-wing up to when the fleet arrives. It might be best to double check the sequence when the Ghosts arrive, because the LUT is there after Palpatine is dead.
