Chosen Solution

I recently had my phone replaced by Apple, twice now due to factory defects, but on the latest one everything seems to be fine with the exception of this very thin white line around some sections of the edge of where the glass meets the metal frame. Is there any way to clean this off or improve this?

That glue is hard as a rock and needs to be chipped off. I would take it back to apple and complain. This phone doesn’t sound like a new phone but a refurbished phone, and it looks like they didn’t do as good job. I would make Apple replace it or live with it. But if I paid 1,100 plus dollars I would expect it to be perfect.
