If the ring were large enough there could sort of appear to be a horizon, because past a certain distance atmospheric scattering would obscure your view. As the ring curved up and away enough you'd be looking at it through less atmosphere so it would be highly visible.

Beyond a certain distance (depending on the atmosphere) it the surface and sky would appear to blend together into a fog. Then you'd see the distant curve of the ring emerging above the fog as it reached high enough in the sky that you were viewing it through less atmosphere.
Kind of like pic related but over a much larger distance.
