LR applies profile corrections automatically when it encounters mu-43 cameras and lenses. The 'Enable Profile Corrections' check box has no effect. After a long lapse that started before I switched to LR, I recently began carrying my Canon S-95 P&S to record things better than I could with my crappy phone cam. Today I did more than a quick-n-dirty edit. While looking for the 'Remove Chromatic Aberration' check box I saw the 'Enable Profile Corrections' box was not checked. It didn't make much difference, but the box will remain checked. Is yours?
