Olympus OM-1, no optical corrections when converted .DNGs are processed in Lightroom 6

If I convert RAW images of my newly purchased Olympus OM-1 to DNGs, the distortions of the lenses (last used: M.Zuiko 12-100 and 9-18) are not compensated in Lightroom. However, the same lenses are corrected in LR if I shot with the E-M 1 II, regardless of whether I edit the original ~.ORF files or shots converted to ~.DNG.

used version:  15.1.1.1329

I attached an original .jpg out of the camera and an image converted as described
