Is 4K HDR Blu Ray quality really so much better than 4K HDR streaming?

I recently just bought a TCL 55R617 TV. I'm just wondering if the quality of Blu Ray is so much better than streaming that it is worth it to buy a Blu Ray UHD player and discs. I've never actually watched a Blu Ray 4K HDR movie, so I can't really compare personally. I'm not a cinephile, but if the difference is significant, then I might be interested. via /r/tech https://ift.tt/2QnjVaV
