UPDATE: Since we originally published this article, Fox pulled support for its stand-alone apps on Roku devices, so if that was your plan to stream the game, you're now out of luck. The announcement stems from a contractual disagreement and it only affects stand-alone Fox apps like Fox Sports and Fox Now. If you use Roku to subscribe to service with live TV channels like YouTube TV or Hulu With Live TV, those should still work for tuning into the game live. Those streams aren't in 4K, however. Luckily, you still have a little time to call an audible before the game kicks off.
This year marks the first time that the Super Bowl will stream in 4K ultra-high definition (UHD). That statement comes with a caveat as the actual production will happen in 1080p and then upscale for compatible devices. Here's the official word from Fox: "produced natively in 1080p 60fps HLG and upconverted to 2160p 60fps. The broadcast will be offered in the FOX Sports and FOX NOW apps in HDR10 and cable/satellite providers in various HDR formats.
