The big issue I have with what you say about the Blu-ray’s accuracy is that there is evidence that the Blu-ray’s color biases in some scenes are not always consistent with the original prints.
None of those scans look anything like projection. Just taking the second one as an example - Reece was nowhere near that dark, he was clearly visible in that scene.
I mentioned that the second frame was scanned too dark, but the others clearly weren’t since their brightness isn’t too far off from the Blu-ray.
Anyway, would you say the projection was accurate to the old German DVD, the one that was transferred from a print? That transfer has a lot more green and teal than most others besides the Blu-ray.
Given your experience watching the film, that DVD release, and the general accuracy of the Blu-ray to the projection you saw, with those frame scans having different colors present, there might have actually been some fluctuation from print to print regarding the blues/cyans/teals and such. It’s hard to say until we get at least one print in somebodies hands to scan the whole film.
