I suppose it’s a bit of an optical illusion. Because the screens are now much better, the depth in the backdrop image makes it appear as though the set itself has much more depth than it actually does. This only works because the backdrop is a high quality image displayed on a very good quality high resolution screen. Otherwise, the image would be too obviously fake for the illusion to work.

It also helps the sharp angles of the set. Now you can barely notice the 'fold' point if looking solely at the screens given how the nice backdrop now can disguise it.
