The only thing I remember (vaguely) is that in the corridor outside our room, between 6090 and 6088, there was extra material on the floor and walls, which appeared to serve the purpose of "sealing" a seam - as if the ship had been joined together at that point, and the extra room in the wall was accounting for that joining.
I hope that made even a little sense - for some reason I'm having a hard time describing it. Anyway, it didn't seem to affect our enjoyment of the stateroom.
