Interesting. I was looking back at my BluRay collection (physical) the other day, looking for a UHD movie to test with, and in my memory, all BDs with UHD, but to my surprise, very few of them were actually UHD, with most just being HD (1080p). I doubt there's in in my collection that are BD100; could I even play them? Currently using a PS5 as my BD player, and PS4 and PS3 before that.
A PS5 can play UHD Blu-Ray, PS3 and PS4 (even the Pro) can’t.
UHD discs are fairly noticeable at a distance as they usually use black disc cases instead of blue. They’re somewhat niche (if Blu-ray wasn’t already niche) and often sell at a premium, so I suspect unless you’ve been seeking them out you won’t have them barring the odd multi format bundle.
