To be honest, I'm not totally sure I understand your note, but I wish I did and I'm interested in your viewpoint.
For what it's worth, I think they're worthy of comparing because they are similar sized spaces being remodeled in the same time period and resort. One is dripping with detail and embellishment and historical charm. The other is quite modern and plain and cheap: drywall walls meeting drywall ceiling, lacking millwork, historic detailing, etc. Given there are pictures hanging on the walls of the Emporium, I'm considering it pretty "finished." I'll be surprised if finish carpenters are coming back to add crown molding or coffered ceiling beams, etc. at this point (unless they get motivated by the criticism!).
But because I'm passionate about this stuff, I'm going to go a step further and make a deeper point about the consideration and thoughtfulness of the DVC space compared to the Main Street space. In the DVC space, if you look at the coffered ceiling beams and where they meet the walls, there's a pilaster there (essentially a half column/surface column, with a decorative cornice at the top, and the pilasters are nicely fluted. This is absolutely spot on, architecturally. Because even though NONE of this is actually structural; (load bearing) it was done accurately/logically as if it was load-bearing (and real). The load -- the weight of structure above -- would be carried by the coffer beams over to the walls and then that load would be carried down by the pilaster (column). That is how buildings work, and whoever did this interior design did their research, they understand historic architecture and building methods.
That is exactly why the original Imagineers were were so good and why Disneyland was so great, because as Hollywood art directors and set designers, they knew real architecture and employed that same experience they used to design sets for period-piece movies (not just for Disney but MGM, etc. too) in designing Disney's architecture (especially Main Street and Frontierland).
Okay, over at the Emporium, those blocky columns and the varying heights of the openings between the spaces, all wrapped in drywall... And the wallpaper on the right side that meets the drywall ceiling with no millwork, no crown molding? That is absolutely not what a turn-of-the-century building would look like inside. It is, essentially, wrong (and cheap, it's both). So, when I look at these spaces, it's not just that one has color and texture and mixed materials and embellishment, it's that one was done by a designer (or team) that are working at a higher level than the other and/OR the DVD space was working with a bigger budget whether in buying materials and construction labor...or design talent.
