I liked the picture quality better when I compared the screens at Worst Buy...
I so wouldn't put it past the BB folks to tweak the picture to match what they want to sell you.
Everything at BB is in torch mode, anyway. They're running in Vivid, or whatever the manufacturer offers, with the blues cranked way up and the brightness so high that it will burn a TV out in no time. No color is accurately displayed.
Some people run these modes when they get home, because they "pop" more, but are horribly inaccurate. And drastically shorten the lifespan of the TV.
