I'm having the issue with my 80-400mm @400mm@@ wide open. The images are totally blurred not due to out of focus but due to having lots of chromatic aberration causing multiple images formed by the cyan on one side, the actual image in the middle, and the magenta on the other side when view at 100%. This is probably my worst lens made by Nikon.
I got a "halo" effect in images shot at 400mm f/5.6 on my 80-400 (which I sold subsequently), and it is something that is similar to what you describe, but it was okay stopped down to f/8. Some others say they're happy with the lens at f/5.6, but when I look at other people's images I still get an impression of not that great detail and clarity. I think replacing the lens might result in a better lens, or not, depending on luck. I think with such a complex lens it would be unlikely that Nikon would do adjustments to it, rather they would replace the interior barrel with all the optics, VR and AF-S motor as one chunk in service, if it were determined faulty. However, it's a 5x zoom lens and Nikon may have set tolerances for it that are more lax than you or I would like.
The 200-500 Nikkor is sharper, but it has a bit slower AF and the zoom is quite stiff, there is no nano coating and the lens is of course much heavier than the 80-400, so it is debatable whether it can be considered a replacement for the 80-400. But it is probably more satisfactory optically unless you shoot into the light, provoking flare.
So far all my Sigma Art prime lenses are spot on with a little fine tuning using the USB port.
Well, they're primes, there is usually very little sample variability in fixed focal length lenses.
