ATV 4K 3rd generation apparently not passing HDR10+
I bought a 3rd generation Apple TV 4K today because I have a recent Samsung TV that supports HDR10+. I also have a 2nd gen ATV 4K that does not support HDR10+. The video setup info for my new ATV shows HDR10+ is enabled and I am using a high quality certified HDMI cable. When I stream content with HDR10+ through the new ATV, my TV reports HDR (not HDR10+). When I stream the same content through a Google TV device, my TV reports HDR10+ and I can see the difference. My source is Bohemian Rhapsody UHD HDR10+, and I've tested using both VLC and PLEX on both streaming devices. I updated tvOS to 16.1 but that did not resolve my problem. Can you recommend a way to demonstrate HDR10+ output from the Apple TV streamer?
