I'd tend to agree with this. Some people see stuff like this and some don't. Whether it's a matter of visual acuity or mental scrutiny, I don't know. But whatever it is, I know I'm one of the people who tends to notice picture flaws. My wife, on the other hand, rarely knows what the hell I'm talking about when I point this stuff out. But she also doesn't care, which may be as big a factor as any.
But it's hard to spend $2,000 on a TV and then "not care".
