IMO they're better than the fake backdrops but still often distractingly fake looking. If your background is really that bad, maybe better than nothing but probably better to try to do something about it, whether a screen or something else.
To be honest, a few things like backlighting windows (and bad lighting generally) are far worse than a bit of clutter.
