That's what it looks like to me, some protective layer to keep the white dash clean and not marred before delivery. Not unlike the protective covers some people found over their screens that didn't get removed. Have to say I have never seen that white dash problem before on here and the Black and White interior option has been around since before I picked up my car in 9/2018 I think.
I have the white dash. It looks like what you have underneath the material that is peeling off. My guess is that what is peeling off is a protective layer that should have been removed on the assembly line but was not.
