According to Fox Sports website, they do NOT support 4K and HDR on Android TV ( https://help.fox.com/s/article/Which-devices-are-4K-or-UHD-compatible ). However some folks in the Nvidia Shield forum said the MLB Field of Dreams game was in 4K and HDR in the Fox Sports app ( https://www.nvidia.com/en-us/geforce/forums/shield-tv/9/461499/fox-sports-app/ ). There is an upcoming MLS All Star game on 8/25 that is scheduled to be broadcast in 4K and HDR, but I will be away for a business trip so won't be able to check it myself. Has anyone here tried to see if 4K HDR works in the Fox Sports app on their Sony TVs? I'm curious for the upcoming Thursday Night NFL games which were just announced to all be in 4K HDR. Granted it is only upscaled 1080p, but it still looks better than regular TV broadcasts. I have a 900H in case that matters.
