Thanks! Have also searched via Google and can come up with no definitive answer. I went out and took a few photos in Raw + JPEG and when viewed at 100% in ACR can see no differences that would be attributable to lens correction being applied, or not. Corrections baked in camera to both RAW and Jpeg could also be the case. After adjusting the RAW a bit in ACR , I looked at the xmp file which was inconclusive to me- one line shows- LensProfileEnable="0", another line-LensProfileSetup="LensDefaults".
Interestingly- the same "photo styles" aka profiles that can be applied in camera on the GX85, can also be selected on the Profiles menu in ACR, in addition to the Adobe profiles. So, I'll just assume that any lens corrections in RAW are being handled automatically behind the scenes, either by the camera, or ACR.
