Remarks

This property only reflects the layer's on/off state in the TOC. A layer's visibility property may be TRUE and the layer may still not be visible on the map. This occurs when a layer is marked "on" but is not drawn in the map display because its display is dependent on the scale of the map.

Use VisibleLayers on IMapImage to retrieve an array of layers that are both "on" in the TOC and visible in the map display.

You can also use MinScale and MaxScale on IMapLayerInfo2 to see if the layer has any scale dependencies and then use MapScale on IMapImage or ComputeScale on IMapServer2 to determine the map scale. If the map scale falls outside the specified scale range set for the layer, the layer will not display.
