Yes, make a photo of something flat. If one side is very OOF while the other corners seem to be in focus, an element might be decentered.

That's one potential effect - one or more elements are more or less centered (the center is where it should be) but tilted.
The other one is a more a global loss of contrast caused by an off-center (shifted) element and that's harder to check in shops.
