Stop listening to people on here who don't even own the new mini led iPad, they're here to troll people by spreading fake news or they've got nothing else better to do, they are going off photos and videos online that are way over exposed, these photos and videos are not what you see in real life.
Nothing wrong with the photo you posted, screen looks fine
Enjoy your new device, the new mini led display is absolutely stunning.
Stop listening to this guy, he is the real fake news. The blooming and shadows are bad. Especially when using in the dark.
