>>> Can you tell if this is browning or damage from improper cleaning?
This is not browning; rather it is physical damages where the skin has been abraded off.
>>> Am I correct in my understanding that if this is damage from magic eraser or other scuffing that there is nothing I can do to fix it?
To fix it may require repairs with Adhesor-73; thereafter a matching luster AnilineTop-21W seals it. Note that Vachetta is unfinished leather; any repairs will deviate from the originality but a good compromise for appearance sake.
