Couldn't agree more. I too have a very nice dedicated setup, and I just recently began to upgrade from 11.4 to full Atmos support, and replaced the 1080p projector (+ 120" screen) w the new flagship Christie 4K unit (and a motorized 15' acoustically transparent high-contrast screen, links to SmartHome) and I have been torn...
On the one hand, watching native 4K content is simply unlike anything else short of giving Homeowner Associations the world over a stroke and building an IMAX dome in your backyard.
However, there's been a dearth of even halfway worthwhile content, and while Netflix "4K" and YouTube 4K and such are obviously better than 1080p content from the same place, because "2160" has a lot more "p" than 1080 and everyone knows that bigger numbers are what we at OCNlive ffor, I feel like I have to take a shower after forcing such a display to "slum it", but there's really not been much in the way of having any actual choice...
So I have had occasional pangs of buyer's remorse, held at bay only by knowing that while inevitable that prices for the equipment drop as content availability increases spurring along mainstream adoption of the standar, I don't expect to see anything comparable to the Christie available for much cheaper in the same way that a 4K LG 75" OLED flagship television isn't going to be all that heavily influenced by 50" 4K LED-LCD televisions and the prices remain far more dictated by the technology and production capabilities and costs than they are by "free market capitalism".
Fortunately, this news!
I think people are making far bigger a deal of the color than it is, because how many people do youtthink own the necessary calibration hardware to ensure accuracy? I will bet that the OVERWHELMING majority of people wouldn't have a clue in the slightest as to what that means, so it is ultimately meaningless as you need only look at current standards to see that the standard is never the problem, it instead comes down to the capability of existing display tech (mostly panels, but projection as well).
I hope that audio is given a far more prominent amount of capacity, there's no reason not to have the absolute max existing channel capacity support (native, not emulate) and at 24/96 or better for every channel.
Of course, I expect to be disappointed somewhat, that way I technically never am
