A possible in-universe explanation for the change in appearance of the bridge: Maybe it´s not a new bridge at all, but the whole bridge module can be lowered into the superstructure for protection. So in the first pic you only see a part of the window, since it´s in the lowered position and in the second one the bridge would be fully extended. Granted, it would make more sense to completely hide the bridge-window from view and possible damage, but still.
Thoughts?
