Perhaps, but I find it hard to believe that plastic lens with such a wide POV has so little distortion that I can't see it on my 30" monitor. I use pro lenses on my Nikon D800 and at that focal length you can still see a difference - and these are expensive (zoom) lenses. I don't have a fixed lens at that focal length lens to try, just a 14mm Rokinon and it has distortion all over the place (but is nicely cleaned up by the profile, thankfully).
We'll see once I do a straight-up profile of the FC6310 next week (hopefully, if the holidays don't get in the way). May also post this issue on the DJI forum and see if they have any feedback.
