Well, finally! That’s assuming support for the P3 color gamut is what it seems, meaning that Apple iOS must support color spaces through and through. But nowhere does Apple mention anything about whether Safari supports color spaces (Safari in iOS never has before), so possibly the support is only in the Camera and Photos apps, and not in the iOS Safari web browser. Still, it may have been added—to be seen.
I’ll take any forward progress; the P3 gamut is a huge bump up in color gamut from sRGB, particularly for reds. Still, the the P3 gamut is weak in eminently printable rich blue colors, not nearly as good as AdobeRGB, which itself has limits with rich blue colors even as printers can print the gamut of images like the one below in full-gamut color.
- Wide color display (P3)
- Optical image stabilization, Six‑element lens, Sapphire crystal lens cover, Backside illumination sensor, Hybrid IR filter
- Quad-LED True Tone flash
- Panorama (up to 63 megapixels)
- Autofocus with Focus Pixels, Tap to focus with Focus Pixels, Live Photos with stabilization
- Wide color capture for photos and Live Photos
- Improved local tone mapping, Body and face detection
- Exposure control, Noise reduction, Auto HDR for photos
- Auto image stabilization, Burst mode, Timer mode, Photo geotagging
The P3 gamut won’t hold the colors in Glacial Blue Lake image nearly as well as the AdobeRGB colorspace (which itself clips the color), but P3 does quite a bit better than sRGB. See Color Gamut Example: Glacial Blue Lake for more on this topic, including a comparison of color spaces.
