It’s official, DISH will be carrying the Super Bowl in 4K on Sunday, February 2nd on Channel 540. No news of HDR at this time. If they don’t have it in HDR I would recommend watching it on the Fox Sports app with either a 4K Roku or a 4K FireStick which will have HDR.
Superbowl LIV , San Francisco 49ers vs Kansas City Chiefs, Sunday 2/2/2020 on Channel 540-01, starting @ 1PM Eastern
"The Masked Singer" is listed on the same channel @ 10:30PM Eastern
And it doesn’t appear to be presented in HDR. If you are capable of that and have Roku 4K or a Firestick 4K use your DISH credential with the Fox Sports app, you won’t be disappointed.
And, just so it is covered, the AppleTV 4K does not have HDR for the Fox Sports app...
