Maybe a new feature on Blu-ray? (this is for blu-ray fanatics)

[Q?]

I read the reviews for Hellboy II: The Golden Army.
Impressed by the review I bought this title, as it was given the best
score in terms of VQ.
I bought the UK version and popped it in, I soon realised that
this wasn't refence quality, I wasn't at all impressed!
although it's stated here that this is fantastic!
After a little investigation I found out that the UK version got a VC-1
treatment

and the U.S. got a MPEG-4 AVC treatment

I was shocked! why isn't the UK version reference quality like the
U.S. version?
I would have definately bought the U.S. blu-ray with the superior video treatment than the almost dull UK treatment!

Maybe a new feature could be added here on blu-ray.com
that compares at least the U.S. and the UK releases that have different video
codecs? or other version's.
How else can you be absolutely sure you've got the best blu-ray disc in terms of technical quality? I know it's too much to ask when your considering
that this is not an official site.
P.S. I really appreciate blu-ray.com and the reviewers for their outstanding work! but at least discuss this problem (in my opinion).
