It depends on the file type. If you shoot RAW, the camera’s in-camera lens corrections are generally not applied to the image data, so you should enable lens profile corrections in Lightroom if you want those corrections. If you shoot JPEG, the camera’s corrections are typically applied in-camera, so Lightroom usually won’t need to do the same correction again. In short: RAW = enable Lightroom lens profile corrections; JPEG = camera corrections are usually already baked in.
