Dark spots on bottom of MacBook Pro with Touch Bar screen

Hey. Hope everyone’s well. I have a 2016 13inch MacBook Pro with Touch Bar and today suddenly when I turned it on there are 8 darkened spots at the very bottom of the screen. I’m so careful with my products and they’ve never been hit or dropped so I’m so confused how they’ve appeared suddenly. I have looked up and I can see there’s been a cases of this happening to the same models and possibly free repairs for the issue. I also lately have been having battery issues and it’s only lasting around 4 hours on a charge so I’m pretty annoyed at paying £1700 for this to be happening. Has anyone an idea if Apple will fix the problem for free? Thanks
