If you have a 4K TV, all 1080p input is upscaled to 4K by the TVs upscaling circuitry. Perhaps Fox’s upscaling of their 1080p signal to 4K prior to broadcasting is a better upscaling of the original 1080p signal? I suspect any differences would be minor and your ability to see them would be a function of the size of the set and your viewing distance.

So, instead of 1920x1080 pixels, you will get 3840x2160 pixels, 4 times as many. This is supposed to produce a better picture than 1080p, but don't count on it. Networks don't want to spend the extra money to produce native 4K content.
So, make sure your TV is set to the 4K resolution to see if you can tell the difference.
