Is Conference room display mode gone on gen4

I have searched all the settings any help would be great since I have 6 Apple TVs?

I haven't found it either. I wonder if this is because it is now considered less appropriate for corporate environments.

If you have any suggestions that you think might enhance the Apple TV you can send Apple your feedback here

We have the same issue - no conference room option found anywhere on our Apple TV 4th Gen even with latest tvOS update.

Not available as per Apple's support documents, since it only supports 2nd and 3rd generations:

Turn on Conference Room Display (Apple TV 2nd or 3rd generation)

1. Make sure that you have Apple TV software version 6.0 or later.
2. On your Apple TV, go to Settings > AirPlay > Conference Room Display.
3. Select On.
4. Follow the onscreen steps to use AirPlay. You can use this display with multiple Wi-Fi networks or Apple TVs.

Has anyone figured out how to get Conference Room Display to work with the 4th Gen devices?
