Behold - torrents of sports (World Cup matches) in 2160p (4K)! - https://www.dropbox.com/s/pvb5f7qe9v1tcpb/FIFA.World.Cup.2018.Group.E.Costa.Rica.Vs.Serbia.2160p.HDR.WEB-DL.AAC2.0.HEVC.ts%201.torrent?dl=0
You'll need a 7th / 8th generation Intel processor (laptop or desktop) or Nvidia 10xx series video card connected to a HDR capable monitor or TV, and VLC (https://www.videolan.org/vlc/index.html) or MPV (https://mpv.io/installation/) to play back this file. There's maybe...three people on the board that have a computer and TV that can play back this file. But it's really cool to look it.
4K and HDR is pretty awesome. You are looking at the future. Finally, there are live sports broadcasts in 4K (depending on your provider) - https://www.theverge.com/2018/6/15/17467958/world-cup-4k-hdr-streams-broadcasts-us-uk-opinion.
I don't think ESPN or Fox will be broadcasting college football games in 4K anytime soon, but things are slowly moving that way. Having all World Cup games broadcast in 4K is a big first step.
