Actually, Quicktime player does not respect aspect ratio signalling placed at the "video stream level" at all. It looks for it at the "container level"... The Apple guys refer to it as a "Transformation" option.

And in-case any of you are interested (with the exception of the Apple TV player) not a single hardware player respects "container level" aspect ratio signalling whether it be .MKV, .MOV or .MP4!
