Is it possible to view the effects of frustum culling dynamically without using the Occlusion Culling system?

One of the great parts of occlusion culling is that you can visualize what is being culled and what is not. You can even uncheck "Occlusion Culling" after occlusion culling has been baked, and see how the camera does frustum culling by itself.

However, I'd like to see what effect frustum culling is having without having to bake a scene with occlusion culling. Why? Because the scene that is being created is dynamically generated. Is that possible?
