I got the 65" a couple months ago for well under $1000 from Fry's. I've had no issues with HDR content, and in a slightly lit room, black levels are great.
Overall, the picture quality is really good, and my only regret is that it isn't a 75" set.
I would love to have it calibrated, as I feel as though I'm missing out on the last bit of color reproduction.
But again, overall, it's a great TV.
