I don’t think it is re dyed
I'm no expert but although I voted to return it I wonder if it is actually the Resin that has cracked not the actual leather? why this would happen on a good as new bag I have no idea and likewise I dont know if the resin can be repaired.
Secondly I did wonder if maybe the bag had been re-dyed White from another pale colour and hence these cracks appearing?
just a thought.
