Purple fringing comes from the lens, not the camera. It can be more or less pronounced, the D500 has more pixel density than the D800 so it is normal that you observe more fringing on the D500 at 100 % crop.

Usually lenses that were designed before numerical photography were not designed to avoid fringing; it is also amplified by the use of teleconverter. I assume that you use the 300 f4 with a 1,7 TC so the result. With a modern lens you'll not have that, instead there are options in post processing (lightroom) to remove it.

May I add,  with these tele lenses, there is some amount of longitudinal chromatic aberration, the suject slightly off focus before has a purple halo, the subject beyond has a green halo, here the branches of the nest are before the focus so the purple halo is a normal behaviour. Only modern tele lenses have a better correction of this longitudinal chromatic aberration.
