For those discussing HDR and the World Cup, Layer3 TV is expanding their normal 4k feeds to include the Fox/FS1 4k HDR World Cup feed. Broadcasts that are normally on the Fox HDR broadcast (ie Rus v Egypt) it's coming across in glorious 60fps 4k HDR.
Layer 3 is available in certain markets, and you don't need to subscribe to their internet package for the cable television. If you can try them out for the tournament I highly recommend it... I'm getting amazing HEVC cable tv (massive step up from comcast), 4k HDR select broadcasts, and I don't have a dish strapped to my house.
Happy to answer any questions, I'm not affiliated but I suffered through comcast long enough that I want to help people step up to something better, especially with how much this panel highlights the flaws in poor video feeds.
EDIT: I forgot to mention you can actually see the difference between when the TV grabs the HDR feed and when it doesn't. During the first couple matches the picture would be intermittently washed out, like others have mentioned needing huge gamma shifts to look right. When it grabbed the HDR feed it would change to my HDR settings in TV menu, and the gamma/colors/brightness would snap into being correct/vibrant. Not sure if it's on the broadcast end or what, but it was interesting to see a feed sans HDR wrapper and how it looked.... sharp but washed out and off.
Looks like Fox isn't using HLG, and I bet layer 3 is pulling the same feed as direct tv, interesting that the dtv set top box wasn't sending the right signal for the tv to enable HDR.
