I can confirm they weren't. I've able to use going back & forth, the seat position more front or back & even have a round control button for lower back support. One thing I've noticed is they ditched the rear passenger lock button from the 2018 a4 model & now have speaker as shown.
From what I know, it’s the same mmi and virtual cockpit used in all the line-up, so A5,6,7,8 and Q5 (probably q7 and q8 as well but not sure). For the A6 they replace the hvac controls with the screen
