4K Digital Movies in my Library
I purchased both The Hobbit and Lord of the Rings Extended Editions through iTunes/Apple TV app on my iMac. I just got a sweet LG OLED 4K TV. I understand I cannot download 4K versions of these movies but must stream them. However, when I look at say the first Hobbit movie in my Library, it says it's HD but when I look in the Store at the same movie, it says it's purchased and available in 4K. Should I delete the HD versions I'd previously downloaded to my Library on my iMac? How do I know I'm actually getting the 4k versions when I play them with my 4K Apple TV? Any education would be appreciated.
