Why is a kabylake or better needed for UHD?

[WatchTower]

I'm pretty sure UHD Bluray players don't have the same specs as a 12 threaded gaming PC with a gtx 1080 We are told BS like we need a kabylake for a PC to play UHD blurays. Even the Xbox One Slim which is like a calculator in comparason to my PC can play them but they don't have high end cpus. I don't get it?

Surely the my GTX1080 SC can handle the horse power to play a freaking UHD? lol

Pretty sure windows has a deal with Intel for this. Same with Netflix, if you wanted to play 4K HDR on windows it required a kabylake or it wouldn't work on Intel or AMD or Nvidia . Nvidia did release a patch that overcame the need for a Intel cpu for 4K but it quickly went "poof". So it's all about the money ;P

kaby lake and successors have the internal 10bit gpu and hdcp 2.2 goodies for 4k/uhd+hdr, and also the trusted platform 2.0 hardware module to protect the aacs blue-ray security keys,
so it seemed a valid security mechanism, albeit helping sales.
(but as posted 4k keys have now been leaked and if you have the appropriate uhd drive could rip copies for personal backup - illegal in uk)
