For those want to test blooming on their new sets, try The Strangers (with Scott Speedman and Liv Tyler). Watch for dark scenes when the creepy killers are wearing the masks in a dark scene, or watch for panning scenes throughout the house, showing lit candles inside. The blooming on my otherwise stellar XVT474SV 3 years ago, distracted me the entire time. After that movie, blooming was always on my mind and it never went away, I started looking for, and noticing it more often than I wanted to admit. But when you're viewing a movie where everything is lit, I never saw a better picture in my life
There were many other movies that a few of us would post in those threads to test for blooming. Off hand, another one I recall was Inception, where he reached into the black safe on the wall, and there would be blooming around his hand, very unsightly
I pray the higher tiered models deal with this better, otherwise I may wait until 2015 to see what strides might me made to tame blooming/halos. If it wasn't for the lack of zones and how the LED lights are used in each zone, nothing beats true, full array local dimming.
Note: I see some people keeping their back lights at 100. I fiddled with my 553 and 474 a lot while owning them, and settled between 16 and 25, or something low like that, Try it out and see how the picture looks,
