I think you need to watch it again. It's a radically different design from the original, owing more to the movie era. The control panels and displays are like the Okudagrams seen in ST IV-VI, the design of the turbolift door and the lower wall detailing is like that of the later movies, Kirk's chair is on the same level as the outer consoles as in the E-A and Excelsior bridges, and the turbolift entrance is on a flat wall rather than in a recessed alcove. So it's not a recreation of the original. It's an attempt to redo the TOS-era bridge with an Enterprise-A-era aesthetic. So it's a new design trying to capture the essence of two old ones.
