Yeah, for a couple of the warp-out shots.
The thing is, no CG galaxy class ever built has been 100% accurate. Most have had pretty glaring innacuracies, especially the "These Are The Voyages" model.
When I saw that teaser, the electrons flew out of my atoms and I dematerialised with shear awe. It looks so gorgeous, I thought I was looking at a perfect CG model.
Unless they borrow the filming model from Paul Allen, 3D-scan it, remove those thingies from the backs of the nacelles, and somehow mock-up the original paintjob, they wouldn't be able to remain consistent with the model work. And, to be frank, I don't think CGI could EVER look as phenomenal as that model.
This teaser has single handedly made me mourn the death of the physical model in Sci-Fi.
