Since the iPad Pro 9.7 supports two Color Gamuts it needs to also implement color management in order to get the second smaller sRGB / Rec.709 Gamut to also appear correctly, which is generated from the wider native DCI-P3. Each display is individually calibrated at the factory. The iPad Pro 9.7 has a very accurate 103 percent of the sRGB / Rec.709 Color Gamut and 102 percent of the wide DCI-P3 Wide Color Gamut. See this Figure for the measured Color Gamuts.
In addition, the iPad Pro 9.7 detects content marked with the wider DCI-P3 Color Gamut and automatically switches between the Gamuts so that content with the smaller sRGB / Rec.709 Gamut is accurately reproduced and not displayed with over saturated colors.
