Yeah, that's it, but the version shown in theaters didn't have the DTS logo zoom back like that. Notice that the entire image pulls back. That was done in telecine when it was transferred for 16x9 anamorphic DVD release, because the framing was tighter on the second half. (I was just a kid then, but I distinctly remember either "THIS THEATRE FEATURES" or "SOUND" sometimes being partially cut off in the theaters where I saw it flat.)
That, plus the general lack of an HD video source for the trailer, is why a 35mm flat copy would be so great. It could be scanned in high-res, synced up with a cinema disc, and included as a separate track set to play before the film if one were to burn a Blu-ray/theatrical DTS sync to BD. It would complete the recreation of the DTS cinema experience.
This guy did a mind-blowing near-4k scan of the original SDDS trailer, with his own DIY rig.
