Have you had the car from brand new? If not, its possible that wheel was refurbished before you took ownership. Lacquer peel would suggest to me evidence of a previous poor repair.
Agree.
It’s not unknown for brand new cars to sustain damage in transit between the factory and the dealers - wheels are susceptible to damage when loading, strapping down and unloading new cars from the transporter lorry delivering them to the dealership. It’s possible that this may have happened to the OP’s car and VW or the dealer got the damaged wheel(s) refurbished rather than replaced them.
If the OP hasn’t owned the car from new, then there’s also the possibility the wheels could be replacement non-genuine replicas. If so, then the quality of finish may not be as durable as OEM and may be more susceptible to the lacquer flaking or peeling from the wheel’s face.
Hopefully the OP will post up some pictures and / or provide an update once the dealer has inspected them.
