You're the one who has some growing up to do: 1) Like a child, you hear the things you prefer to hear instead of what you are told. 2) You seem to think the world owes you things. You get upset when those things aren't delivered to you as you expect. 3) You seem to think you have the right to tell people where they can and can not participate on an open forum. 4) You can't seem to wrap your small mind around the concept that whether it's HDR10+ or Dolby Vision (which my TV does support), I have no expectation that a $150 USD device issued three years ago will pick up support for it. Not going to happen. One can make an arguement for a $3,000 USD TV. Even a $1,000 USD receiver. Not a $150 android TV box that's three years old, has been replaced by a newer model, and does not have a large distribution. The more expensive, better supported, Nvidia Shield doesn't support HDR10+ either. The same can be said for Apple TV, and the Roku Ultra 4K. If you want HDR10+ support, just buy a Amazon Fire 4K and move on with your life. Being an adult is about accepting the things you can't change. Try it on for size.
