Does segmented dimming work when in play mode to headset in unity?  
Or does it need to be installed on device to work?

@janikows Happy to help with this.

The segmented dimmer is not supported in editor or application simulator at this time. However if you can describe the use-case and impact on development I can share your feedback with our voice of customer team.
