It's a bit hard to evaluate for me: when standing the pedal feel is and keep different to the feel when driving.
When driving I got a veeeerrryyyy slight intermittent screaching like a slight inbalance on one disc.
And I got the feeling that if I first press the brake pedal after driving some meters the reservoir level goes down by a very little bit.

So maybe the investigation should include a possible inbalance of one brake disc...?

Imbalance can't do this, but a warped disc could cause an effect like this, but only a very slight difference.

However, if the caliper sliding pins are wonky it could cause an effect like this.

Ok, finally problem solved: it was air in the system.
During the service they couldn't find anything strange at the discs or pads and after bleeding the system today the brake works much earlier with a strong pedal feel.

Thanks for all your hints!

Yes, definitely! A 15-minute-repair is highly appreciated!
