I think you are VERY naive about how the broadcast, cable/satellite, and streaming industry works. They all work at a snails pace. Broadcast and cable/satellite are not likely to offer 4K HDR, and if they do it will be through a streaming app side service. Streaming companies usually have their core subscribers addicted to their service, and are not too worried about losing them. They will proceed at a snails pace, especially since they well understand two other factors that are involved. One, there is a very limited amount of 4K HDR material available to stream, and two, most people still don't have the equipment necessary to stream 4K HDR. The same thing happened with the introduction of HDTV. Had the FCC not stepped in and forced the content providers to convert to digital HDTV, we would likely still be watching a lot of SDTV programming. The FCC has shown no indication of forcing the adoption to 4K or 4K HDR. The industry will continue to proceed at a snails pace. Once enough content is being offered in 4K HDR, we will see the pace increase, but currently there isn't much 4K HDR content even available.
You have a great deal of nerve calling me naive when 1) everything you typed has nothing whatsoever to do with the issue, and 2) I've been at this a while, and know what I'm talking about.
I'm more than aware of the issues getting 4K content out via the various means, and the differences between those means. My point is that Apple is lagging in getting the *available, already out there content* to display properly.
Example - FOX 4K content, which has been available with HDR and, i believe 60fps, for literally years now.
On ATV via FUBO: The 4K content not only doesn't trigger HDR, but squashes the color space horribly.
On ATV via FOX app: Same
The same exact content on other client devices works. I know my HDR chain works (i.e. the various HDCP / HLG handshakes etc), so it's not something with my setup.
Of course, i realize it takes 2 to tango on these apps working, but when Apple came out with the 2021 4K ATV, they literally cited this was going to be fixed on the new hardware. All I've been asking - where is the progress?
Improved Video Experiences
With A12 Bionic, Apple TV 4K now supports high frame rate HDR (High Dynamic Range) and Dolby Vision video, enabling fast-moving action at 60 frames per second (fps) to play more smoothly and appear more lifelike than ever before.1 Apple is working with leading video providers around the world, including FOX Sports, NBCUniversal, Paramount+, Red Bull TV, and Canal+, as they begin to stream in high frame rate HDR
