Assuming that the image on the upcoming BD releases has the same problems, how would you go about fixing this?
The colour adjustments applied by Adywan and Harmy on their theatrical reconstruction attempts has failed to address this particular issue (sorry guys).
Referring to the first shot with the crushed balcks, you cannot simply raise the black level, as this produces some ugly grey artefacts (this was one of the problems with OCPmovie's Classic Edition V2). Although this effect could possibly be reduced by applying a dither, or error diffusion, to the dark areas of the image.
As for the second image with the unnatural colour boosting, I don't think there is an easy way to fix this using any overall image adjustment.
