The more I look at that first picture, the more I don't see a corner there at all. Judging from the shadows being cast, I believe a very strong light source is coming from the far right side of the picture. So it's possible the shading we're seeing behind the combo unit is actually the drape edge casting a long shadow on a straight wall. Also the lamp shade casting light on the wall does not appear to be bent by the apparent corner, it looks nearly symmetrical on both the right and left sides.
