Clean Zoom Rooms display outs?

I thought for sure that I heard that the connected displays to a Zoom Room on a Mac Mini had 3 display outs that would be totally clean?

They are clean for me until a 3rd person joins the call, then there is the names displayed on the screen, the number of participants, and a mic muted symbol if the Zoom Room mic is muted, and an NDI bug if NDI is being used.

I am trying to get three displays from my mac into my ATEM via HDMI and was hoping that the outputs would be clean.  Was I mistaken?

I'd rather not have to go through NDI > vMix > Outputs > DisplayPort > ATEM via another computer, just too many things that can go wrong in between.

Thanks
