True. Fortunately I have that with my current TV (a Sony 2015 year 4K passive 3D model). However the 3D crosstalk is barely acceptable for my eyes. High contrast and low black levels tend to show up ghosting. I fear that to achieve really low crosstalk with a high dynamic range, active glasses may be a necessary evil. (I also suspect that there may need to be a step up in the left right alternation rate of active glasses for 3D to be really effective with HDR.)
I'm actually caught twice as I have a slight preference for curved screens! I was admiring some Samsung 4K screens in a showroom the other day and really appreciated the curved screen versions. As for basic PQ, the series 6 Samsungs were impressive for their PQ and the series 9 even more so. However as you've pointed out, the Series 9 is being restricted to a flat screen version...
In the home, I'm prepared to live without a curved screen, but I refuse to be deprived of 3D!!
Im just about to start the Front Wall build. Just finished the speakers today. Chipping away at slowly everyday. Cant believe how many hours I've put into the room so far from pre wire to now etc. Its fun though There is a back log of videos I will upload on all this to my youtube channel sometime soon.
The trouble is tv manufacturers dont know how to set a standard and stick with it . Only now with 4k do we have the option of passive frame packed 1080p,24 without heavy 2k active glasses and the tech cost has been amortized . Now we get to wade through the mess that is multiple 4k HDR iterations as the ce's never seem to learn ; what fun Anyone who has a 3d collection is left by the wayside ..
They obviously know whats good for us .. a good ce would give a choice depending on viewing angles etc .. just like 3d imho
