Just rewatched Harmy's ROTJ version 1.0 and there were some issues that should be fixed in a later release.
- The composition off Luke and the Rancor is the 2004 version: the matte lines at the Rancor's legs are missing, and the colors are matching. The original version had prominent matte lines and mismatched colors.
- The hand-painted black blobs at the sides of Palpatine's face also are missing (they were removed in the 2004 version, IIRC).
