Howard, I think I read this for a Post Tim (BM) made. Edited my original post.
OK, found it, my bad, I was reading between the lines
, and Howard you asked Tim if it was the same sensor, no reply. Here is the reference:

That is the current range. We are driving the sensor differently to how it has been done previously, more similarly to a traditional broadcast camera, and are happy with the results we have been getting out of it at each of these settings.
You will need to update your ATEM switcher and software to 7.3 and the camera to Camera 5.0 Update so that these line up correctly between camera and switcher.
So his comment about driving the sensor differenty, implied they are using the same or similar sensor previously used, is where I got the idea it was the same BM Studio 4K sensor, again I am reading between the lines here. Sorry for the confusion.
Cheers
