Though it might be worth comparing the framing of the Reliance demo reel. Because apparently the D+ streams are 2.39:1 vs. the normal 2.35:1 they have been on prior releases. I hope that this is only a quirk of the streaming version.
2.39:1 has been the actual 35mm anamorphic standard since about 1970, but 2.35:1 kept getting used for years even though it was no longer correct. All the OT movies probably should actually be 2.39:1. It’s pretty much an imperceptible difference between the two anyway.
You can really see that switch when comparing the Bond movies of 1965-71 and 1977-2002.
