Ray,

it is my understanding that the crushed blacks are unfixable using the blue ray as the source. See hamy's making the despecialized Star Wars Youtube to see why. The detail in the black areas is just gone. ANH:R suffers the same problem.

however as ady has shown with the restored cockpit shots, he has access to a HD film scan of ESB. Therefore from that source the information lost in the crushed blacks is still present. A lot of work to restore.... But it could theoretically be done.
