Just for reference, here's what I get with closer subjects from the old doubler - Canon 1D MIV + 400 2.8 IS + Canon 2x TC II, 800 mm, f/5.6, ISO 1600, 1/320 sec, 475B/516 support, manual exposure in available light, processed 100% crop, less than 5 m distance.
I obviously can not say how much better you could get with 2xTC MkIII, if at all, on that sort of a proximity shot. (Incidentally, I believe the bird in that shot was frontfocused slightly, assuming that you aimed for the eye, and not for its flanks ).
If you shot something , say, 60 ft distant, then the resolving power is being tested at a distance which really warrants a deployment of an 800mm combo, and I'd be trying to explore the IQ in such medium (and long) range shots, as opposed to proximity shots.
