How are people watching films these days? Is anyone still buying Blu-Rays / 4K or just streaming?

I have a rental subscription with Cinema Paradiso which I hardly ever use, but thinking that I should keep it going.

I have a 4K Apple TV which I love and use for Apple, Amazon and Netflix. I still have an HD621 with a cheap 4K splitter which I'm thinking of upgrading to a UHD722, mainly because I have picked up a Control 4 remote system which I want to set up once.

Cheers
Tom
