As the title says, will the night shift allow you to colour correct the screen to your liking? I found that my iPad Air has a yellow hue to it already, so it would look disastrous to make it even more warmer. I often found myself JB the device and using colour profiles app to correct it, so was wondering if night shift is apples fix for the dreaded yellow screen? I've seen videos demonstrating the device getting warmer, but I've not seen results that could turn the device cooler, and fix a already yellow hued screen. Or does 9.3 completely recalibrate the screen to more blue, that will fix the yellow hue without having to slide the nightshirt mode to cooler?
