Need some help with a culling problem

For my understanding everything behind my camera should be getting culled by the default Frustum Culling system.
Grass is being culled but not buildings and characters etc…
I should be able to see this in scene view right? I see the grass being culled in scene view.
Not sure what I’m doing wrong.

Oh i see now. I need the Occlusion culling window open to see it culling in scene view.
