    This is my second Pro as the first had the same issue. Basically 1/2 of the screen is warm and the other side is cold. So right now as I'm looking at the keyboard, the left half looks red/yellow and the right half looks blueish.

    It sounds minor, but on light backgrounds reading from left to right and having that color shade change from yellow/red to blue can be jarring. I'm quite far from an Apple Store so I was just going to see if Best Buy could order a new one for me.

    Has anyone experienced this?

    Mine is like this. I've gotten used to it over time, but yeah it's a thing.

    Thanks for your honesty. I might still try to return one last time, but I'll wait till the last moment to see if I can get used to it.

    Sure seems like that would be hard to get used to. I use the Kindle app a lot for reading and this would drive me nuts, not to mention cause eye strain. I question why you wouldn't return it - if you ever wanted to resell it, this would resuce its value.

    I tried an Air 2 recently and returned that for being too slow. Next I tried the 2017 and that didn't work due to eye strain. I swapped that for a Pro...which had severe color temp issues. So I went back to Beat Buy AGAIN to swap out for another Pro that has color temp issues. So this is my 4th iPad in about 2 weeks time.

    I'm getting a little tired of the returns...but this ones still pretty bad so I'll go through one more round. If that doesn't work, I'll drive up to an Apple Store and go from there.

    This is simply the state of LCD panel production -- sometimes you get near perfect white point uniformity, but it's just luck and is the exception instead of the rule. The type of uniformity you want simply doesn't exist in the panel price range that these types of devices use. Even high end consumer monitors which cost $1000 have the same uniformity issues, and I haven't seen any improvement in this era in recent times (device manufacturers keep asking for better display specs, so the manufacturing yields never improve). If you want perfect uniformity you'll be looking at $10K for a professional-grade display, and the cost is mostly a result of them having to pick through the panel lottery for you.

    The iPP adds another layer to the uniformity issue because its AR coating application is never perfectly uniform, creating a "clouding" effect similar to what you see on plasma panels with AR coatings.

    It bothers me too, but there's currently no solution except for Apple to pay more for tighter uniformity tolerances. OLED isn't any better, despite what people say; the panels display a high level of uniformity variance, but it's primarily current response variance instead of a cool/warm white point gradient (though some S8 users are seeing that too). Samsung attempts to cover this up by using PWM (flicker) dimming, as the panels become less uniform as the current decreases. Flashing the display at high brightness to handle dimming allows them to mask the issue, at the cost of enough flicker to give some people headaches.

    My point is... good luck finding a uniform display. They are out there, but it's not the norm. Apple may humor your efforts up to a point, but because you didn't buy the device from them your resolution will probably come in the form of a display panel replacement, which will have the same chance of showing uniformity issues.

    Thanks for the in depth response.

    I didn't notice this issue in the Air 2 or the 2017. It's just the 2 Pro's thus far. Tho the 2nd Pro's color temp & brightness variance still bother me, it's not as jarring as the first Pro.

    I will try one more time.

    Thing is, I had Dell IPS panels from 2007 that may not have been perfect, but I specifically remember marveling over how a dark red screen looked the same across the entire panel. I have an iPhone 6S Plus that's not perfect either, but it's MUCH better than these Pros.

    I think Atomic Walrus is right.
    I had two iPP 9,7 and they both had a light brown/yellow tint coming from the left side. The iP 2017, i actually have in use, has a light blue/gray tint coming from the left side. Also, none of my iPhones (4s, 5s, 6s) had a perfect Display. Our expectations seem to be to high in consideration of the price tag.

    I'm not happy about the situation, but knowing that it's an issue for some of you helps to alleviate my OCD about it. :)

    So I'm in my way to the store and considering getting a 128GB instead.

    Partly because of the $100 off sale, so it would be the same price. Partly because 32GB is kinda pushing it.

    But I'm wondering if:

    The NAND solution will be faster much like larger SSD sizes.

    But most importantly, perhaps I would have better luck with a more uniform display?

    You know, the whole, $$ toy gets the better screen conspiracy!

    Well, I went with the 128GB and it still has the same color temp difference from left to right I'm portrait mode.

    I guess I'm just disappointed because my phone doesn't have it. The Air 2 didn't have it, and neither did the 2017 iPad.

    It's very distracting and I don't think I'm asking to much to have a uniform color display on a small IPS tablet. I've had plenty of IPS monitors without this issue and I even a VA TV that looks fine.

    At this point, I don't the no it's worth returning again as I'm sure it'll be the same situation. I just can't believe I've seen no mention of this in reviews and a lot of sites says no the Pro panel is one of the best displays out there.

    When reading from left to right and back again, I see warm to cold, then back to warm...I'm tempt d to take it back and wait for a new Pro.
