Do you mean that the sky colour is wrong? That's a bit of a difficult one to assess because at low altitudes we always see through a lot of atmosphere. Setting no fog is a bit like removing _all_haze from the view, which is something you'll never see in real life, except perhaps at very high altitudes. Removing the fog is a bit like elevating your altitude. It may not be perfect but you'd be hard pressed to do much better with a fully featured ray-traced renderer, let alone OpenGL. Don't get me wrong, with ray-tracing you could account for variable refractive index and scattering based on altitude and wavelength but it would take a long time.
