Macbook 2015 12 inch Screen

hi folks, new to this so excuse me if this is not the thread to ask on but i have a 2015 macbook 12 inch and have recently noticed an annoying little thing on the left of the screen right at the end . i don't think its a dead pixel but appears to be something that hold the screen in but this i can't spot any anywhere else, does anyone have this or can tell me what it is? its hard to see in the photographs but its just above the torch reflection I've used to highlight it. thanks, kevin.
