And I never said it couldn't have been, a post refit version.
Which makes arguing it rather odd.
Though IF the Bridge was the same as the one in the fleet museum, given the design differences between the bridges used pre and post, i.e. only one turbolift pre compared against two post, it COULD indicate a pre-refit version.
Without seeing it, we can only guess.
I think the holodeck computer chose a version of the original Enterprise
bridge that was most famous historically--during the midst of Kirk's 5-year mission. Otherwise, it could have been any version of that bridge from as early when Pike was in command or as late as the V'Ger Incident, IMO.
