Auto Iris Control is available only at Television Studio 4k8

we have Television Studio 4k8 and when double click "Auto" at Camera Control it works great.
(Controling the iris between sensivity and coarse setting. thats realy cool)
But our Blackmagic ATEM Advance Camera Control Unit doesn't has this function.
also ATEM software doesn't has this as well.
Why only Television Studio 4k8 has such a good function?
