IPhone 7 display is more warmer?

Did the iPhone 7 display is more warmer than previous iPhones? Is that normal?

You can fix it in settings

Hmm, don't think so. During the manufacturing process, sometimes the screen can get that yellowish tint or blue tint. Annoying--but only if you noticed it.

It's an easy fix, follow these steps: Settings > General > Accessibility > Display Accommodations > Color Filters > turn it ON > select Color Tint > adjust the Hue according to your liking > lower the Intensity.

Warmer in terms of what?

Colour tone or temperature?
