I cannot find pictures of my previous devices to show, but if you just Googled it, you would find results mentioning this exact issue:

Has anyone experienced some discoloration in the iPhone X in the Stainless still band? It seem like a oil stain but it won't go away. Sorry for the picture quality, the best I can do with my Surface Pro 4

It could have something to do with the salt in sweat that is causing this.
Edit: I just noticed that you are the OP asking about this issue, so I guess you were just saying this ironically, so sorry for misunderstanding!
