According to a new research note from

displays like in the 9.7-inch iPad Pro currently.
Apple's new next generation 2017 model iPhones like iPhone 7S, iPhone 7S Plus and iPhone 8(iPhone Edition) will feature True Tone displays like in the 9.7-inch iPad Pro currently.

Barclays believes that the iPhone 7s, iPhone 7s Plus, and iPhone 8 with OLED
display will each have a ‘full spectral sensing’ ambient light sensor for a
‘True Color’ screen which are expected to be supplied by Austrian semiconductor
manufacturer AMS. 

For the expected iPhone 7S models, as well as the iPhone 8, we think ams’s
content increases due to the inclusion of its full spectral sensing ambient
light sensor, as already seen in the iPad Pro for that device’s True Color
screen functionality. We estimate this to be a material step-up in content from
the $0.60 range to $1.00.

9.7- inch iPad Pro is the first iDevice that feature True Tone display using
advanced four-channel ambient light sensors to automatically adapts the color
and intensity of the display to match the light in environment.
