To me it looks like I might have backlight bleed at the bottom of the screen.
Is it really an issue?
Based off those pictures, I definitely think you have light bleed in various areas. Rather it bothers you or not, it's up to you and if affects your work/personal experience with the MacBook.
3 days but then again, do all screens have some sort of bleed? I think if I exchange it, the next one might have some too.
Not all screens have light bleed. Some are more minimal than others. Some never think to look for light Bleed. If it bothers you, then take advantage of the return period or Contact Apple. If you have the mindset that the next MacBook will have issues with something, you will likely find it.
Your pictures looks like it has more than I would accept.
I feel like at a normal glance, people can't really notice it. So if Best Buy customer service ask me why I am exchanging..I am not even sure what I should say or show. This will be my 2nd exchange at Best Buy within the 14 days exchange period lol! They'll probably think "wtf this guy is exchanging again." but yeah this is really bothering me, every time I am on a white page. the bottom looks blackish with shadows.
