I just got mine from Abe's of Maine. BF deal at $6k.
No dead pixels on mine, no panel light leakage, no dirt behind the screen.
Slight banding in the middle upper left part of the screen.
Panel consistency is ok, but I am coming from an XBR46HX909 that is a great monitor.
4k upscaling from an OPPO-105 is pretty amazing on the panel and motion is amazing, smooth and no jutters.
Blacks is OK compared to the HX, but good on this size panel.
I used UK HDTV's setting suggestions and it helps on blooming and banding, but off angle viewing is not as good as the HX.
