Lightroom still doesn't have a lens profile for DJI FC6310 camera on the Phantom 4 Pro drone.
Correct. DJI recently began using opcodes in newer models to store lens corrections that Lightroom and Adobe Camera Raw can read and apply directly. There is no need for an external lens profile. If you click on the "i" on the bottom of the Lens Corrections panel, it will show a dialog that explains which lens aberrations are being corrected by the opcodes.
