Netflix is "4K Ultra HD: Up to 7 GB per hour".
Blu ray is 25GB per side, so max 50GB for 2 layers. Typical movies are 35-50GB.
So, BR, and think even DVD still looks much better than any streaming service!
We’re going to have to disagree about DVDs though. They look awful on modern (big) televisions.
Are pressed Blu-Rays limited compared to writeable ones?
I have 100GB BDXL blanks (single-sided) I use as one of the archives for my family photos/videos.
Couldn't a film BluRay also be 100GB on a single side?
Very out of date list: https://forum.blu-ray.com/showthread.php?t=294596
On a site that I am a member of there are nearly 1300 BD100 rips available.
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.
