Apple is pretty much the only company that cares about this it seems, I honestly wouldn’t be able to tell the difference between 4K HDR content available on iTunes/TV+ vs Blu Ray.
If you subscribe to Paramount+ in the TV app, you get the entire library in a higher bitrate compared to actually using Paramount+, it’s incredible how unwatchable some shows were bc P+ basically just thought 1080p 8mbps H264 was good enough for everyone.
