If only because its not a durable coating so you can wear and scratch through it. Easy enough to replate but personally I don't like the idea of coatings that easily scratch off revealing a different color even if in this case it would be very subtle. There is a reason why PP moved to unplated wg eventually.
I totally understand, I prefer all the other white metals to wg, but in this case I would just leave it or pick a different watch. The plating is suboptimal and getting a platinum case or black dial would likely be costly enough you'd be a good chunk in your way to another watch.
