iPhone 12 Green Tint || Display Issue

Hello everyone!

I finally received my iPhone 12 on October 20th and immediately noticed that I was effected by the now infamous green tint issue plaguing many iPhone 12/12 Pro units.

Many have reported that they've gone in and gotten the whole unit replaced, which ended up changing absolutely nothing. However, I still went to Apple - earlier this month - to get a replacement as I was curious. Everything went smoothly. Replacement was free of charge, no questions asked, and it was a display replacement - NOT the entire unit, which I was happy about.

They swapped displays in store and the process took an hour or two. When I got my phone back, even with the bright Apple Store lights, I could tell that the issue was gone. Blacks displayed properly and grays were actually gray. There was no green tint at all. Days later, I notice the green tint again when restarting the iPhone. This was the first time I'd seen it since. I dismissed it, for whatever reason I came up with at the time. However, as time went on, I noticed that grays were a little more... Well... Green.

I dismissed that as I thought I was just being paranoid. Nope. Not even close. Turns out, the green tint issue slowly came back.

So, here's what I'm asking:

A) Has anyone gotten just a display replacement? If so, what was the outcome?

B) Did you notice this tinting return, assuming that the new display initially fixed the problem?
