Funny you should say that, I've just checked the text messages you receive from the dealer when they send you your visual inspection video.
For my first service back in May 2019, it said Front brake pads 40% worn, rear brake pads 40% worn.
From my service in May this year (same dealer) - Front bake pads 30% worn, rear brake pads 30% worn
So it looks like without my spec'ing it VW fitted my car with self regenerating brake pads as well
