If so, yes. ACR/LR work differently for Oly and Panny µ4/3 lenses than for any
other lenses. The distortion data from
the manufactures, as used in their firmware for JPEGs and in their Raw
conversion software, are baked into ACR/LR. They
don't show as profiles, and can't be disabled.
Very interesting! I figured that the profiles would be available in
the normal lens profile section, but they aren't.
Nope, what you get is what OlyPan want you to get. I assume Adobe did a deal, official correction data in return for
baking it in, so it can't be turned off. ACR/LR users, and those of Oly and Panny Raw converters, then think all those
lenses have minimal distortion.
If you look closely here:

ACR and SilkyPix both do a less than complete job. Look at the line of the top of the central colonnade; it's slightly
bent. PTLens is better, and DxO is perfect.
Also of note to someone like me is the difference in how they are corrected. ACR/LR and SilkPix leave the center
untouched, increasing correction with distance from center. DxO and PTLens make the center smaller and the outer areas
larger.
I would say, though, that those Panasonic lenses I have, with or
without correction, do a remarkable job. I'm quite elated with the
quality of pictures I'm getting. However, I'm not getting the OMZ
look/feel that I prefer. Close, but...
They really are making excellent lenses.
