depends on your camera. Some cameras have DLO built into the JPEG processing so you can turn that on, and it should help your JPEG's. Otherwise, no, it needs the RAW data if you are doing it in post processing on your computer. The RF mount cameras do this much better. as the DLO data packet is stored in the lens itself and downloaded in the camera automagically. with other DSLR's .. i think you may have to load the lens profile manually into the camera.
See, I loaded a lens profile for the 85 1.8 into my RP (firmware 1.4.0) and noticed no difference in LOCA or PF with or without DLO turned on, when making in-camera JPGs, which led me to believe that it's only helpful when shooting RAW (but even then, I can just use the profiles in Lightroom CC).
