Yes, it does the fine control (about a 20% range) as a separate bias from the gain set on the MFD gain rocker switch and it’s done that for a long time. And we know it does TGP “smooth zoom” which is more recent (AAQ-??).
I wish I had a -1F-16A-34 to see what the controls did exactly originally. I remember the A-10A to C transition changed a lot of controls, the Mav polarity switch became exterior lights, countermeasure became autopilot, etc.
