Why get obsessed about this? If I scrutinized every dinner plate, bicycle, pencil, calculator, hairbrush, pair of trousers, laptop, girlfriend, motorbike and banana that I've ever had in this way, I'd go insane.
If you have the habit of holding an object at strange angles or in unlikely lighting conditions in order to detect flaws, it isn't the object that is flawed.

I paid $1200 for an NEC Pro (90) series LCD. If I turn out the lights and put up a black screen it does the same. Do I care? NO! Yet it is the number one thing I see people complaining about on LCD forums. They put up black screens in dark room and complain it isn't perfect. Often they run cameras for multiple second exposures to prove how bad theirs screen is.
Really if you obsess over little things like this you will never be happy. Maybe look into OCD meds.
