Possible goof.

Has anyone else noticed the amount of times we see the top of the set and support beams in Devon and Ellie's apartment? I remember noticing it first in "Chuck Versus the Lethal Weapon", so I checked on IMDb and sure enough it was listed as a goof, however, on re-watching the show, this same mistake happens so many times (pretty much every scene set in Devon and Ellie's apartment features this mistake at some point), in some cases, it's so noticeable (Sometimes the Camera is pointed directly up at the ceiling to reveal wooden beams across the whole frame) that I wonder whether that's just what the ceiling of their apartment is supposed to look like? Although it's very rare that roofs are built on movie sets, and I doubt that Devon and Ellie would have a black ceiling (unless that's a thing in America) so is this just something that the production crew don't care about and let slide? I wouldn't usually mind, but it's so distracting now and it can really take you out of a scene.

After all that nit-picking, I feel that I should add that I do think this is one of the most entertaining shows put on TV in a long time.
