Wait a minute... your go-to scene for testing contrast is one where the screen strobes rapidly between light and dark? Doesn't that just bork your irises all to hell, where a Wal-Mart rear-projection from 2005 would look contrasty? Wouldn't a scene featuring linear or point sources of brightness be a much better choice?
(One YouTube TV tester did some actual testing using reference sources designed for this use, and found that light blooming is no better than the previous generation, and light evenness is worse, especially with off-axis viewing.)
I'm not saying these are terrible TV's, but they still have limitations on contrast that haven't yet been fixed.
