I'm imagine if it was a different class of ship, it would also have different jeffries tubes. I think the Enterprise, Defiant, and Voyager tubes are all styled differently, but consistently with their ship. Not to mention the DS9 tubes would have to be different because they were designed by Cardassians (and built by Bajoran slave labor).
The first two are completely different areas, one is a junction, the other is an access tunnel. Why would they be exactly the same if they don't have the same purpose?
