I actually thinks in some ways the regional sets actually look better than the national set which just suffers from being far too big and looking somewhat cold and sterile.  The regions are adopting a similar look but with so much more warmth.

Possibly down to the lighting, B does appear to use some rather cool white LEDs, as well as the backdrops having a bit more colour to them.

To be honest, it wouldn't be the first time that regional sets have worked better in certain respects. I know they're sometimes maligned, but I think that the 2009/10 faux-Barco regional sets were nicer than the national Barco sets (particularly TC7 in News at Six mode). The newsroom lightboxes were quite well done (even if empty) and provided a cleaner backdrop than the Barcos, and the use of red in painted form is preferable to the overly bright red lightboxes that adorned N6 (luckily, since the move to NBH, they seem to have worked out how to get a deeper red through lighting).
