Well in the past I’ve heard people say you can try ‘massaging’ the affected area, I’ve had limited success like this myself and usually a stuck pixel is something you have to live with. Highly doubt they would change it as it wouldn’t be deemed a fault as you are allowed so many dead pixels on a screen without it being classed as faulty (the figures for this are on google if you care to search).
Mine came with a couple small air bubbles in different parts of the screen. Though it might have been the ‘other’ screen protector but I don’t think thats the case. Annoying as well!
