Not last I heard. The original negatives degraded. And the restoration process was solely done to create the Special Edition, so they didn't restore it unaltered.
This is why the last release of the originals, on DVD, were from the laserdisc masters. They're the only copy of the originals in any worthwhile condition.
The idea of a "unified whole" is merely an excuse for rewriting our cultural history. It does not deny the accusation.
