It seems like the wallpapers on the new 9.7" iPad Pro are Adobe RGB (displayed as P3).
Beyond that, there's probably nothing that the average user can notice yet, at least until iTunes UHD content comes this year or next year.

They might also add support for css colors in P3 color space. (css colors are currently always sRGB).
