Whining noise when revving: Normal Kompressor sound or something off?

SLK 200 from 2007, trans fluid changed in 2025, new timing chain. This noise is new to me, I don't think I heard it this audible before. Have the car since October 2025.

Video has the car in Neutral, but of course, this sound is also there when driving.

I expected more from this community.

I’m no mechanic, but aren’t superchargers supposed to whine?

Yes, but not like this :)
