    On supported devices like the iPhone 7, it seems that you don't get the larger color gamut on wallpapers even if the image has the DCI-P3 profile assigned.

    Below is a DCI-P3 wallpaper in Photos and then as a lockscreen wallpaper; exposure and display backlight was locked.

    Source Wallpaper (if you want to try it on your device, the difference is much more noticeable in person)

    I agree with that! If it were the color gamut, I shouldn't notice any difference on my 5s screen.

    I doubt it is the wallpaper problem. The bug (or feature) with wallpapers being selectively dimmed should not affect the saturation of colors.
    (Edit: My original reply sounded a bit snarky, sorry about that.)

    I did some measures of the Red primary and anything larger than the sRGB/Rec.709 gamut gets remapped (downgraded) to that.

    The last "Y" is luminance (brightness). Notice that it barely changes for all the measures.
