This really doesn't have anything to do with Blu-ray as a format. A given title may not be owned by the same studio in any given country i.e. the rights to a Fox title in the US might be owned by Warner in the UK etc. Not really a whole lot you can do in that situation. Even if it's the same studio, that doesn't necessarily mean that the title was mastered in the same location, or even that the same master might have been used to produce the BD.
