SetCameraCullingPlane() does not modify the Plane index
How to reproduce:
1. Open the attached (CameraProperties.zip) project
2. Open the "SampleScene" Scene
3. Enter the Playmode -> see the debug.log in Console Window -> Exit Playmode
4. Select "Main Camera" in Hierarchy -> In Scene Window move the Camera
5. Enter Play Mode
Expected result: SetCameraCullingPlane() output in the Debug.log is different than it was before moving Camera
Actual result: SetCameraCullingPlane() output in the Debug.log is the same as it was before moving Camera (see CameraProperties repro.mp4)
Reproducible with: 2019.3.2f1, 2020.1.0a23
Notes:
- SetShadowCullingPlane() appears to not work as intended too
- Could not test on 2018.4 because of errors on the Script

Resolution Note:
The described issue arises from how structs work in C# (they are value type). Both ScriptableCullingParameters and CameraProperties are structs. CameraProperties is accessed through a public property on the ScriptableCullingParameters. To get the expected behavior you thus have to write the properties back;
void DemonstrateApproach()
{
Camera.main.TryGetCullingParameters(out ScriptableCullingParameters p);
Debug.Log($"before: {p.cameraProperties.GetCameraCullingPlane(0).normal}"); // prints before: (0.7, 0.0, 0.7)
var properties = p.cameraProperties;
properties.SetCameraCullingPlane(0, new Plane(Vector3.up, Vector3.zero));
p.cameraProperties = properties;
Debug.Log($"after: {p.cameraProperties.GetCameraCullingPlane(0).normal}"); // prints after: (0.0, 1.0, 0.0)
}
