Maybe this is overkill and not necessary to include on your list as it already mention that the opening was redone three times, but I found it interesting that the digitally re-composited elements for the '97 SE differ in the same way that the 2004 lightsaber impacts did or the '97 saber impacts on the Falcon.

Original on top / SE below

(The color on these impacts is only green due to the overall bad color-timing on the 2004 transfer, they were all yellow in the '97 transfer.)

The 1981 re-release opening is identical to the original when it comes to these laser and blast elements.
