Probably not. It takes a lot of pressure to bend an iPhone 6. If you have AppleCare+ then they might replace it under that for a slight fee but typically that sort of thing would be considered physical damage and not be covered by any warranty.

Maybe but the only way you'll know for sure is to go ask.

Of course not. It's not a manufacturing defect.
