Comment (by Cosmin Stejerean):

 Here are some other P3 images that appear to have the same ICC profile as
 the test sample I shared, from https://webkit.org/blog-files/color-gamut/

 https://webkit.org/blog-files/color-gamut/YellowFlower-P3.jpg
 https://webkit.org/blog-files/color-gamut/Italy-P3.jpg
 https://webkit.org/blog-files/color-gamut/Iceland-P3.jpg
 https://webkit.org/blog-files/color-gamut/Webkit-logo-P3.png

 for all of these along with the one I shared running `exiftool` shows
