Minor update:

The SCOPE print came in the mail a short while ago. While I haven’t had a chance to properly scan it, I did open the reel to skim the frames and observe to color timing. Here’s what I’ve noticed:

It is the same trailer that Paramount features on YouTube. Despite this, the grading isn’t consistent with either their scan of the trailer nor the Blu-ray/previous home releases. Some shots are more partial to the Blu-ray’s colors, others are definitive proof that the Blu-ray is largely inaccurate.

When comparing my print to Paramount’s scan, it looks as if there is a general blue tint in the Paramount YouTube upload; the exterior shots of Bikini Bottom are the most indicative of this. Conversely, live action shots in the SCOPE print are a lot more green compared to any other release I’ve seen, to my recollection.

So at this point I’m going to have to go off of Both Paramount’s scan of the trailer and my own personal copy as references, despite their contradictions. What I really need at this point is a Cam rip of the film, which I’m sure exists but is currently nowhere to be found online. With that I’d be able to find a compromise for the grading on some of the more questionable shots.
