That’s a good point that I own a 4K Bluray player now. I never had an Xbox One S, I had the original Xbox and PS4, so I only had Bluray not 4K Blu Ray. And Into the Spiderverse would be a great showcase actually.
It just feels silly to get a 4K Bluray when I don’t have a 4K screen yet. Though that didn’t stop me from owning CDs long before I got a CD player. Or a Matrix DVD long before I got a DVD player. Or a Ghostbusters Bluray long before I got a bluray player. So maybe.
