iPhone 8 - uneven display?

I know I know, every year you see people with the threads saying “mine is definitely orange at the bottom!!” and every year I roll my eyes thinking yeah right... but this year it’s happened to me!

I took a photo of the screen, honest opinions, does look look more orange/dark towards the bottom?

I can’t un-see it. I know it’s the very definition of a first world problem but when you’re still shelling out like £700 I feel you’re within your rights to ask for an even screen..?!

Let the abuse commence
 
There should be no abuse from anyone. It does look uneven, and I am sure its not the camera angle the pic was taken or else you wouldn't have bothered making this post... I'd give it a few days to possibly fix itself, otherwise exchange it. Apparently there is plenty of stock.
 
Thanks. I’ve had it since Friday and it’s not changed, I’ve just booked an Apple store appointment for Thursday so if it’s not better by then I’ll see if they’ll exchange it
 
Yes, it's the same yellow bottom 3rd that seems to happen to every single iPhone release. I went through 4 iPhone 7+'s and they all had it to a certain extent (although on 1 of them it was magenta which was worse as it really washed out colors).

You can try to play the exchange game, but this is very prevalent in the cheap edge lit LCD's they use.

Oh, and if someone says it's glue drying (like people always do), it's not.

If Apple pushes back saying "I can't see it under this pristine Apple store lighting", don't take no for an answer. They can almost never see it (even I have a hard time) when under all the light at the Apple store.

Yeah that is my concern, that I'll be like "Look at this screen! This.. perfectly.. uniform..screen.." because of the bright store lights.

Well if the worst comes to the worst I guess I can just ask for a refund, use my 6S for a month or so then try again with an 8 a bit further down the line!

Since you are within your 14 days, you don't need a genius bar appointment. You can just go and say "I want to exchange this" to anyone that works there. If you go to the genius bar, they can only attempt a repair. At least, when I went to the genius bar when I first got my 7, they told me the system makes them have to try to repair first and then they told me to just go to any regular employee to just exchange it.

With that being said, if you have to do it 2-3 times, they'll basically force you to go to the genius bar route (what happened to me), luckily, the display the replaced is better than the displays that were on the phone straight out of the box with regards to the yellow issue, even if it's still slightly there.

But ya, go exchange it, that looks to be a more extreme variation of the issue.
 
First world problem maybe, but you shouldn't have to accept a screen like that on a new phone. Mine is slightly dingy at the bottom but looks a lot better than your phone and I'm considering an exchange. Within the first 2 weeks of purchase Apple will take back or exchange for any reason so you should have no problem getting a new phone.
 
I’m just very wary of ending up in a constant cycle of exchanges Ah well let’s see what they say on Thursday, night even ask if I can change to a gold while I’m at it?!

Good luck I went through he exchange game on my iPhone 6 many many times. Each one being the same or worse ina different way than the other until finally I got one I could live with. It's just the nature of the edge lit LCD Apple has been using for years now. Good luck!

Can exchange or return for any reason in 1st 14 days. People exchange because they decide they want a different color or different size. As long as you're getting a new phone anyway you might as well change to the color you want.

Yes bottom left, a bit bottom right
 
#1 reason I am waiting for the X. I'm sick of Apples shoddy LCD manufacturing process. I'm hoping the new screen tech doesnt suffer the same fate. (I've seen Samsungs latest phones and if the X looks like those screens then hell yeah).

Not really a solution that...

I’ll pop down to the Apple store this evening, I just hope they don’t make me wait outside the store behind the velvet rope of embarrassment again like I did when I collected it in the first place
 
So they don’t have stock to do a swap at the moment due to having “lots of reservations”. Yet I can go online and reserve one right now from scratch!
 
Your display definitely is orange at the bottom then fades to what a regular display should look like. They better take care of you!
 
He keeps looking and saying it looks fine, I’m like I know it does right now under these lights but it doesn’t always!! He’s gone away to check something else

I feel like a fraud now as it really doesn’t look bad under these lights!

I had the same experience yesterday. 2 technicians said they couldn't see the issue and it was barely visible under the bright lights, but I could still see it. I put True Tone on so it would show up better but that didn't make much difference. The technician even did a diagnostics test on it which said it was normal but all that did was let us look at the screen under different colors which does nothing to help see an uneven screen. Just remember to stand your ground. You can return or exchange for any reason in the first 2 weeks so don't settle for a screen you are unhappy with no matter what they tell you.
[doublepost=1506454297][/doublepost]Also, I said yesterday that my new screen is perfect. I don't think they are ever "perfect", just good enough and a screen you are happy with. Good luck with getting a screen you are happy with today!

But when I was researching the Note 7 before the issues cropped up with that phone, I saw a few complaints on Note 7 forums about uneven displays as well. I don't know how that could happen, but there were a few posts about it.

It can happen because, contrary to popular internet mythology, OLED is not less prone to uniformity variance in manufacturing. As with all display tech, if you want near-perfect uniformity you'll be throwing away the majority of the panels, and thus paying quite a bit more per display. There are endless threads on XDA about this OLED uniformity problem going back several generations, just like MR is full of LCD uniformity complaints.

Samsung's OLED screens don't have great uniformity. It's very similar to what you're seeing with this particular LCD panel -- usually about a third to half the screen will have poor voltage response, and as a result be slightly dimmer. These areas also experience significant "black crush," which means that anything near-black just doesn't render because the subpixels don't respond to those very low voltages.

They cover this up by running the panels at near full voltage (full brightness) and using PWM (flicker) to dim them, which is why Samsung OLED has to use flicker dimming. Someone tested this last year by rewriting the dimming code (on a rooted device) and discovered that, when running the panels with non-flicker dimming, the uniformity variances became highly visible.

My point isn't that one is better than the other, or that you can't see some visible improvement in uniformity by moving to OLED (many people are more bothered by the LCD-style backlight variance than an emissive display's pixel response variance). I just wanted to make it clear that both technologies are highly prone to uniformity variance; this is the state of display tech and manufacturing practices. There will always be something to nit-pick, and the best you can do is get a unit that's average or better and forget about it.

-----

OP: As others said, the camera can make things appear worse, however -- at least on my screen -- that's about as bad as I've seen the backlight uniformity on a recent-generation panel. You're very likely to get a better display with an exchange. At least, it shouldn't be worse.
