I don't think anyone thinks you are petty, Bogy, I certainly don't. I can see and understand your frustration. It might help if you posted your exact equipment, make, model number, and how you are connected to the TV. Is it direct HDMI or are you going through an AVR?
I am interested in your Netflix statement. I just tried Netflix from my Hopper and got 2160 (UHD) to my Vizio. I always use Marco Polo as my test vehicle. If I watch that directly from my Vizio app, Apple TV, or Roku, it will always be Dolby Vision, Netflix's HDR of choice. When I tried it from the Hopper, it ignored the HDR and showed plain 4K. You should have the same result. Once again, your equipment and how you are installed can help us figure out what is going wrong.
Now, it is important to understand that the Netflix and Olympics issues are apples and oranges. Netflix is merely an app supported by the Hopper and it gets its signal via the internet. The Olympics is actually a satellite driven signal. As I have mentioned before, HDR via satellite is a brand new technology. I am certain that there will be a way detect non HDR TVs and send just the 4K signal to the TV in the future. Please post back and add the equipment that you are using. Help could be on the way...
