Exposing HLC settings in the Camera Settings dialog.

Can you expose the Highlight Compensation (HLC) controls of a camera in the "Camera Settings > Advanced > Imaging" section?

When HLC is turned on in some cameras it makes the WDR and BLC modes unavailable. This keeps WDR from turning on without a good indication as to why. In the camera's web interface it provides a popup saying WDR can't be turned on when HLC is on, but nothing like that exists in the Cameras Settings > Advanceddialog.

Does ONVIF report this feature or is it a proprietary setting to the camera model?

I first noticed this issue of not being able to see the status of HLC and therefore control the WDR mode on a HikVision DS-2CD2065G1-I.
