Earlier quoted context omitted.

To provide additional resistance to corrosion/staining.

That sounds unlikely. It's not how stainless steel works; to bond a coating to the surface of the stainless you have to fight the stainlessness pretty hard.

One of the best indicators for not so stainless stainless steel is a coarse texture to aid in that bonding. Even some fairly expensive brands of vacuum flask exhibit this. Only way to be sure that I know of is a knife.
