Good observation.  I'd have to stick up some calibration charts to tell things like that and that is such tedious work I won't do it unless the lens has to be well centred, such as, for landscape or architecture.  So mid and long telephoto I don't worry unless an OOC lens is obvious in the field.  A couple of lenses from Pentax I've owned have been notably good and there was one lemon that I sold off a while back.  I don't tend to own a lot of OEM lenses.
