I am fairly sure that most micros would add a different strain at bottling than they do at primary. IIRC, LCPA uses a lager yeast as their bottling yeast. Alot of primary strains that give the flavour profiles breweries are after will also be a little too "loose" on the bottom of the bottle, think homebrew and that cloudy second glass. It is a rather large assumption, but I would assume that most filter their beer to get the clarity demanded by aussie drinkers, then either add in a very small portion of the primary yeast, or a small portion of another yeast that is very flocculant.
Your best bet will be to find some bottle conditioned local ales/lagers that you like, and email them, telling them you are a home brewer and would like to culture up the bottle yeast, and ask if they can tell you if it is their primary strain, or a bottling strain. They may tell you that it is a secret, but they may actually tell you for sure one way or the other. That would save alot of hassles of culturing up a yeast that either isnt suitable for the beer you are after, or you can buy dried for $3 or so a pack.
