Just for kidding… if you want a perfectly exact experience, don’t use the official blu-rays: they are encoded at 23.976 fps, not 24 fps… Otherwise you’ll loose about 1 frame every 6 minutes (that makes an entire second on the whole movie… the same kind of inaccuracy as 2.35:1 vs 2.39:1)
I guess you have no other choice than buying a 35mm projector and the original 35mm reels if your goal is to perfectly match the theatrical experience 😃
JEDIT: AFAIK, the original Star Wars (1977) was supposed to be seen at 2.3942856:1. But the SE has another ratio (2.3913042:1).
When digital intermediates were made at 2K in 1997 (and reused for each version since 1997), they were supposely done at 2048x858 pixels at 2K (or 4096x1716 pixels at 4K) according to the DCI specification for the Scope picture container. That ratio is 2.38694639:1…
So for the same movie, you’ll get 3 different ratios. Good luck with that 😃And don’t forget that the SMPTE standards changed the lens aperture ratio in June 1976: it is pretty obvious that most theaters didn’t get this change in 1977 when SW was shown (see http://www.widescreenmuseum.com/widescreen/apertures.htm).

Thank you! I will have to sit down and absorb all this great information! Yes a film projector would be the ideal thing, but try explaining that to my wife 😃
