Well, there's the whole part where this isn't true... Any plasma made in the last 5-6 years has been rated at a 100,000 hour brightness half-life, same as any LCD. That's like 10 years of watching tv 24/7 before your screen dims to half its brightness. As for the "pink splotches" this was an issue from 2011 model Panasonics, and it wasn't even noticeable in actual content, just if you had a solid white screen up. I have a 2011 model ST30 that exhibits this issue. You wouldn't notice it in a movie if you were actually looking for it. It was minor and only discussed because plasmas dont generally have any sort of uniformity issues of any kind. By comparison, i'd bet a paycheck that your LCD has backlight uniformity that is far worse by comparison. It was noticed mostly because plasma owners tend to be videophiles.
Not compared to a plasma. You can barely even tell my ST60 is turned on ,with a solid black screen in a completely dark room. the black is completely uniform as well. There is no situation where you would notice the black bars on a blu-ray movie. VA's have decent blacks in comparison to a typical shit IPS panel that can light a room with its black levels, but not in the scheme of things. VA panels also have bad viewing angles, and they still have the same motion issues as any other LCD.
All of my friends have LCD's and I'm not remotely impressed with any of them. The only ways in which any of them are better is that they get a little brighter (ST60 still gets brighter than you'd even want, can you say 20,000:1 real contrast ratio?). but that comes at the expense of black levels and is really only beneficial if you have your room lit up like an airport. Plasmas on the other hand, you can turn the contrast all the way up for a brighter picture, and your black level wont budge.
