Return of the Jedi starts out with the SW zooming into the distance higher in frame, taking the crawl with it.
Then when they pan down to the moon of Endor they needed to re-time the pan (see DS), just at the end, to get to the same resting point.

Here are some of the finds in DIF-ROTJ 2004 vs 2019 found through 5/8th of the movie.

The left Imperial Officer had his shirt painted black to remove a bright spot from onset lighting:

This might be a 2011 change, but R2’s dome has a frame realigned:

Several sequences of shots suffer from a form of stretching or scaling. In this shot of Jabba and Boushh, the right side of the frame is aligned but the left side goes out of alignment, which could mean zooming in/out. And yet a similar shot a few frames later is less affected by this stretching.

This Luke/Bib shot suffers the same stretching/scaling but in the opposite direction, right is unaligned.

A bunch of shots are realigned:

This C-3po Barge Announcement Power Window might be a 2019 addition:

But this type of power window seems to be removed from Jabba/Leia:

The new scan brings back this electrical fires flares which in 2004 became a white blinding blob:

But maybe HDR blows this detail back out.

Example of how blue 2004 was:

In the middle of the movie, one of the multiple ship SFX shots got cleaned up.
Upper left SFX matte in 2004 left a white patch for a ship which never got inserted.
On the right they cut the shot, which in 2019 they extended to full width of the visible frame:

One of the 2004 blue power windows when Luke and Leia are talking is removed in 2019:

One of the Endor wipe shots got zoomed in more than usual:
