There is no argument that Android phones have made great progress over the last couple of years, with powerful hitters from Samsung, Huawei and Google's own Pixel line, providing phenomenal mobile photography. They typically get close to Apple's iPhone camera if they don't shut it down completely, but there's an area where Apple's cameras still do a little better job.
Capturing photos on a modern iPhone has a much wider range of colors than similar Android devices, as Apple uses a P3 color scale. The P3 series is about 25% larger than sRGB, which is standard for everything else.
The downside of using the smaller color space is that you lose some of the extreme colors and if you see an image from an iPhone On an Android phone, you will just lose some of the living as the phone screen is trying to show everything it can with a more limited color space.
But it may change with Google Pixel 4, although it has been smoked since a P3 gamut photo was leaked from a Pixel 3 despite the fact that the phone couldn't actually use that feature. But now some code in the updated Google camera app is downloaded on P3 color recording, which was then recompiled with the on and tested feature on XDA. That means yes it works on a Pixel 3, and yes, it must definitely be supported on Pixel 4 and hopefully some other Android devices. Devices like Galaxy S10 still support 100% of the P3 color scale on the screen.
This will not be a difference night and day on pictures, but it will add a little more pop and color accuracy to your photos. Absolutely something to be excited about.
