Bug Physical Camera settings from script

Good day,

I'm having a hard time enabling Physical Camera option in Camera component.
It works flawlessly from the Editor, but the

Code (CSharp):

1. usePhysicalProperties = true

does nothing.
Is there a way to toggle Physical Camera from the script or force update upon Camera after setting given boolean?
Is that a bug or this behavior is intended?

Thanks in advance!

 

https://docs.unity3d.com/ScriptReference/Camera-usePhysicalProperties.html

you need a camera instance

 

Camera component is added to the GO instantiated in the scene.
What I'm trying to achieve is exactly this:

Code (CSharp):

1.  Camera cam = gameObject.GetComponent<Camera>();
2. cam.usePhysicalProperties = true;

In the new project it works as intended, I guess it some other local interference.
