I have found out that while current iPhones (X, 8, 8plus) shoot images using dci-p3 wide gamut color, the videos are still BT.709, which is sRGB equivalent for TV. Why is it so? All current top apple computers, tablets and phones use wide-gamut displays, capable of displaying dci-p3 gamut, so it would be nice to have wide-gamut videos, right?
