LCD screens all have uniformity issues and backlight bleed to some degree. This is a fact. So what you are saying is just a lie. Im not overblowing anything, read any review for a LCD panel and you will see they all suffer from uniformity and backlight bleed issues.
Like I already said, yes, OLED panels are prone to burn-in, I never said otherwise its the nature of the tech. However it is not as common as you believe. If you are aware of how Burn-In works its easily avoidable just like it was avoidable on Plasma panels. Just because you read a few posts on the internet saying OMGZ OLED burn-in don't touch an OLED screen it will get burn-in blah blah blah does not mean it happens often. The chance of you getting burn-in is probably the same percentage as having a major issue with an LCD panel, that is pretty low.
