Question: are shows broadcast in 4k?
Answer: Broadcast TV doesn't yet support 4K, let alone HDR. However, there are now some set-top boxes from cable companies, including Altice (Optimum) and Comcast (Xfinity), that support 4K via apps and streaming. ... Dish has fewer 4K offerings—mainly on demand—but it is presenting the 2018 World Cup from Russia in 4K with HDR.
