I just checked and Apollo 13 as far as I can tell is not available in 4K on iTunes. I was thinking the same thing as I bought the UHD today.It refers to DEVICES AND SERVICES access anywhere. Not countries. As soon as Canada gets a hollywood you guys might be treated as equals but until then you have to understand that there are ridiculous legal, economical and other factors that make it completely sensical that services will start in the country of origin and roll out from there. In the grand scheme of things the only claim Canada has here is relative location, many many other countries are economically more important to these services than you are.
Having purchased Baby Driver in 4K on iTunes I assure you it's there on Apple TV.
Anyway. I have an Apollo 13 code to turn in, 4k. From Universal. I should redeem this on iTunes right?
