I was not aware of the second effect - interesting. With global loss of contrast you mean that the whole image frame is affected evenly? If so, it is really hard to check because one would need a second lens to compare the contrast levels. Low contrast alone could just be a normal "feature" of the lens.

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.
