Well, I got my replacement KS9800 65" yesterday and set it up and I didn't wait for this one to have a problem. I stuck Sheldon's calibration settings in and tweaked a few things and watched a crap load of HDR movies. One thing i will note about this 65" curved screen. Off angle viewing, at least to me on this particular set is "FRIGGING AMAZING"! I might not be as sensitive as some to washed out colors and fading from an angle as some are. Our viewing distance is about 7 1/2 to 8' straight on to the center of the screen. We have a big couch centered to the tv and then a couple of large recliners set within about a foot of that couch on either side. So those chairs are roughly 18" off the edges of either side of the screen and sitting in one of them i'd say they are approximately at a 45 degree angle to the center of the screen and i see absolutely no change in color intensity or contrast at those viewing points. the picture is just sublime at those angles. I found my JS8500 from last year to be almost exactly the same.
Based on that, I'd tell anyone considering this set, but scared about the viewing angle wrecking the picture to go somewhere and check that out in person and see for yourself. Now part of what you will see in a B&M store would be those BS super bright dynamic settings the stores use on their display units. In a more controlled lighting environment like your living room I think you will be pleasantly surprised how good the picture is. And i did this in lower level lighting and then cranked up all the recessed LED's in my ceiling and found the picture to be almost identical. Those led's are 11 watt each and make the room appear to be outside they are so bright. Amazingly, there is hardly any glare on the set sitting in the center or in those side chairs. And from a super bright room to one that would be more like a dark room with biased lighting the picture changes very little that my personal opinion is that there is no loss of color/contrast or viewing enjoyment.
This TV, and it is truly my first high end set, has an awesome picture almost no matter how i change my lighting and viewing angle. Granted this has all been all HDR movies except for a couple of older blu-ray's (avatar, kick ass and upscaled 4k total recall). The HDR movies i have watched or checked stuff on so far are ( the martian, mad max, the lego movie, The 5th wave and spiderman 2.) I'm going to pop in Deadpool and the new UHD star treks later.
I have watched a bit of regular tv and a little 4K off of my direct 4k box also. Things looked really good. I haven't played anything we'd consider bad source content so i cannot comment on that yet. Haven't streamed 4k content from netflix of amazon yet either, but i will get to that in the next couple of days
Based on this 1st 24 hours of viewing i give this set 4 thumbs up and an easy 9 out of 10. I really thought i would be bugged about the curve but i honestly can't complain about my viewing experience at all so far.
The picture clarity just floors me. It is so bright/crisp and colorful with tons of detail in both bright and darker scenes. I was gonna be all over the 75" sony after the VE shootout the next two days, but based on the crazy price i got from amazon at 3733.00 plus tax i don't know if i'd even consider the sony now, for yes a larger screen but also about 2k more out of my pocket. but we'll see. unless this set starts having issues quickly, i'm thinking this one is a keeper.
I've not noticed any blooming that would be a distraction or haloing. The black bars, top and bottom, i'v yet to notice any change/white light in them. This tv just has a superb all around picture. I did notice that my firmware on this set is only 1105 and it does not show the HDR+ option as yet. no big deal at this point. i'll see how that is when the fw update rolls it into my set.
