Second, if rotors are anything like our 4 pot rotors, there's a small amount of play in the pin. The gap you show in pic one doesn't seem too far off snug. I'd bet it's just worked its way out a little bit and is flush against the securing pin on the inside. Should be able to tell if you remove the wheel and turn the steering wheel so you can get a view of the rear side of the rotor.
Just making sure since you have a W204 in your sig.
I'd never say 100% no issue to worry about when it's something as important as brakes, but I'd be willing to say odds are in favor of no issues. If you have the means and are really concerned, I'd pull the wheel and take a peek. I just inspected my brakes and pulled them apart 2000mi ago and one of the four pins was similar to your picture.

Awesome. Thanks again for taking the time to share that. Not overly concerned at this point, this system is just so new to me that I’m trying to ascertain what is normal.
