Django Unchained? difference between US version

[The Phantom Goat]

Are there any differences between the US and Canadian blu rays of Django Unchained? My girlfriend accidentally order the canadian one for me, and I just want to make sure there isn't some sort of quality difference in PQ (or anything else) before I open it. I've tried to look online, but aside from explanations of special features, I can't find much else.
