I had no idea that there was 4K versions. Since I don’t have a 4K TV, I only watch the Blu-Ray versions!
FYI, you can get regular 1080p versions of 4K77 & 4K83. I neither have a TV or PC that can play 4k, so I’ve been watching the HD versions of the 4k scans.
That’s really cool! I feel so guilty for not being here regularly. 😦
