Rental copies - Are they different?

[MasterKaga]

I bought a used rental copy of "The Rite" (2011) on Blu-ray and watched it last night. I was floored by how good the copy looked. The blacks were deep and detail was incredible. The audio was impressive too.

But, I went to the menu screen and realized that there are absolutely no extras on the disc. Nothing. Not even a proper chapter select screen.

My question that brings me here is this: Are rental copies different in quality that retail copies? I have no way to compare a retail copy with this one, but I was wondering if anyone here has ever heard of a rental copy being of superior quality to a retail one? I could definitely say that the artwork on the back of the case is way better that the colorful retail one.

Oh, and I could report that my computer reads that "The Rite" disc is 28.1 GB of data.
