Theatrical mix on Blu Ray v.s. DMU

[subwoof]

Can anyone enlighten me what, if anything, is done to modify a theatrical mix when it goes to Blu Ray? Assuming I had the proper interface, if I play a 5.1 Blu Ray disk back on a proper dub stage, would it sound the same dynamically and balance-wise as a printmaster playing back in 5.1 from the DMU? (assuming I was listening to the Dolby Digital track on the Blu Ray)

I'm curious because I watched Mission impossible 3 on Blu Ray this week on my stage, and it sounded like a TV mix. The explosions, gunshots etc were in some cases lower volume than the dialog, any yet other films such as "Super 8" and "Iron Man 2" sound very dynamic and much more theatrical in my room. I wondered if M.I.3 was purposely "dumbed down" for release on Blu Ray, and if other films are likewise dynamically compromised for release.

Thanks in advance!
