I had a quick look the other day and couldnt really see profiles... I'm sure the forum responses were hinting that the camera lens have information built which translates into the RAW files which then lightroom can utilize..
See here...

It looks like if you haven't already tried, to just use the light room "enable profile corrections" tick box that's in the develop module. The forum seems to confirm this, in that settings are pre-applied that the user can't change, therefore only tweak further on what the software has already performed.

This is interesting too, seems to show that the uncorrected m4/3 images are horrendous before correction, hence the need for automatic profile correction.
This reminds me to upload some images of the 40-150mm pro I borrowed before Christmas, what a beast of a lens!!
