About a month after the iPhone 18 Pro and iPhone 18 Pro Max reached stores, a run of complaints about display color has started piling up on Reddit and YouTube. The phones have landed mostly positive reviews, but a vocal set of buyers say their screens look off: too cool, too green, or just washed out compared with what they expected from an iPhone.
Apple buys its OLED panels from two suppliers, Samsung Display and LG Display, and there's no way to pick one over the other at checkout. Apple says both are calibrated to the same standard and built to identical specs: ProMotion with adaptive refresh up to 120Hz, a 2,000,000:1 contrast ratio, and brightness that tops out at 3,000 nits outdoors, with 1,600 nits peak and 1,000 nits typical. Those numbers match the iPhone 17 Pro line exactly. On paper, which factory made your screen shouldn't matter.
In practice, some buyers say it does. A Reddit user posting as junglehypothesis described an iPhone 18 Pro Max with what they identified as an LG GH3 panel as looking hazy and green-tinted, with colors they called cartoonish rather than accurate. The same post laid out a hierarchy of possible panel variants supposedly used across the 18 Pro line, from Samsung's G9N at the top down to LG's GH3 at the bottom, with the GH3 described as more prone to tinting and dimness at an angle. It's not clear where that breakdown comes from. Apple has never published panel-bin detail like this, and the claim hasn't been verified independently. The same user says swapping the phone for one with a Samsung G9Q panel fixed the issue instantly, no diagnostic tool required. Another Redditor, evilZardoz, separately reported a noticeable magenta cast on an 18 Pro screen next to an iPhone 17 Pro.
