Good catch about the Archer bridge! I didn't even remember that we don't see the bridge. What they did to modify the Enterprise bridge – swapping one of the segments for a custom one with different lighting – is actually pretty clever. I wonder if they ever ended up using that set piece in a later episode.When it's not displaying anything it even has a yellow grid. Though I believe the Disney AR wall has a grid too, I believe it's for camera tracking.
Also that PDF shows that they had modified part of the Bridge set to represent the USS Archer in Episode 1, but we never saw the bridge of the Archer, must have been a deleted scene.
Looking at these images, I realize i miss the engineering set from season one. Did they abandon that for season two or did I just miss it? What I hadn't realized is that the huge circular element in the background was supposed to be the back of the deflector dish.
