It's like my one friend who insists that playing files in FLAC format makes them sound like they're being spoken by an angel. I can't tell the difference between a WMA, an MP3 or a FLAC, except that they get increasingly larger and take up more space on my hard drive. But to answer your question, I would think a movie theater would present the film in surround sound, yes.
The first number (the 2 in 2.1 for example) is the amount of treble speakers you have to emit the majority of the sound. The second number (the .1 in 2.1) is the number of sub-woofers/bass speakers connected to the system. This goes back to original audio in film as mono (1.0) sound, then it upgraded to stereo (2.0). Stereo 2.0 is the standard for most standard definition videos until later DVDs, when compressed 5.1 (five speakers, one sub-woofer) was added.
The quality in audio, when you add channels, is a vast improvement. For example, if you have 2 channels/speakers creating ALL the sound at 320kbps then despite how much on-screen action is occurring, you'll only ever get a small 640kbps sound quality - and all of it lost in a messy blur within the two speakers.
Now put the same sound through 6 separate channels at 320kbps, with bass notes ONLY in one channel (A dramatic improvement in speaker quality due to treble notes not being vibrated by a different audio type), you then have 320kbps of pure bass and 1600kbps of treble audio - AND that treble sound can be made to flow around you in circles to really thrust you into the centre of the movie. It is a huge leap upwards in quality and immersion of sound.
There were DVD-A format discs which were not playable on DVD players - they were Audio only discs (An upgrade from music CDs that never took off) which had a six channel sound mix (5.1) uncompressed. The expense of buying a system plus the DVD-A player and discs put people off, but it can (and has) been done more cheaply (for the consumer) on Blu-Ray with the release of The Social Network soundtrack on BD. I have a few DVD-A's, and they are a universe better than stereo CDs. But like everything else, people only buy at a price they feel they want to afford and understandably, DVD-A technology was WAY too pricey to take off.
You'll likely reply with "I don't care" or some such thing, and that's cool. Not everyone will care for the difference between 2.0 stereo and 5.1/7.1 surround sound. Some people are happy to be able to hear it, and that'll do. I will assume (perhaps wrongly?) that you're one of those people. However surround sound audio isn't really to be sniffed at in the long-term. With movie soundtracks it places you in the middle of the film (TMNT in surround sound is an absolute dream - especially during the fight sequence in the rain. Stereo can never compare), and with audio music it can create strange and awesome effects while producing a higher clarity than stereo ever could. Tubular Bells in it's 5.1 DVD-A format is the best it's ever heard, and it'd be a day 1 release if they were to resell it on Blu-Ray because it really does showcase the improvement superbly. Some other DVD-A tracks can also create effects like feeling you're being suctioned into a vortex in the centre of the room and other such weird things. Stereo can't do this, because it's flat sound. We may have only two ears, but we hear in 3D - you can tell when someone is talking to you in front or from behind without opening your eyes - and surround sound lavishes listeners with more complex, better quality and more in-depth audio than stereo.
I've only ever heard SMB in stereo - it sucks because it's obvious huge amounts of background clarity is being lost in the mix. It was created as a showcase movie, it had rudimentary surround sound in it's original mix. A 7.1 DTS-MA soundtrack on a Blu-Ray would absolutely be an improvement because it would allow each of those sound channels to shine and reveal the level of detail put in by the film-makers - thus improving your favourite film without adding or removing anything. Actually providing you more of what you love than not. SMB was made for Surround Sound. I think it's bad that we haven't had a surround release yet, and the fact we haven't is a detriment to the movie you love - because it means executive/company handling has blocked quite a bit of the message and vision you cherish to begin with.
