Other than the lighting, painting and touchscreens, was there any difference between the two bridges?
The turbo lifts have moved even farther apart, almost to opposite sides (neither will really fit in the shape at the top of the Enterprise model any longer, but that’s a whole different issue).
they also lowered the Helm console by a few inches, for better sight lines on the actors sitting there.
this post over in Trek Art shows the differences well.
