People holding out for the originals are gonna be disappointed they haven’t been touched since the laserdisc master in 1992. The restoration was the 1997 edit. No restored OT exists.
The best you can hope for is team blu. I can’t fathom the mind of George Lucas on this nor will i try to psychoanalyze it, its just so bizarre.
To be fair, the Light & Magic trailer on YouTube does show the Death Star explosion with no Praxis effect, which I’m pretty sure is what the comment above yours was referring to. I believe it is also in the actual series, also, and not just in the trailer, but I have not yet watched the series. In addition, I believe it is a possibility that when the '19SE master was created, the new master created was digitally backed up without any alterations. I may be wrong, though. I believe I remember reading somewhere that the unaltered footage in Light & Magic was not sourced from Despecialized or 4K77. This may bring more credibility to my guess, or not, depending on personal opinion. Make of that what you will.
It’s in the actual series itself also. I’m pretty sure all of the footage they used is the actual unaltered material.
There was a rumor back around 2015 that Lucasfilm was going through every last piece of film footage they had and cataloguing it. I’m sure they have, at the very least, a raw scan of some type of print of the OOT, even if they haven’t spent the money to restore it.
