Spectrum of Samsung S7 phone screen taken with CCDSPEC Spectrometer 31/7/2018 – in order from left to right, this represents the peak for blue, green and then red on right. It is similar but not quite the same as the spectrum for the iPhone X when compared to internet sources for the latter (see http://www.displaymate.com/Spectra_41a.html) – I have not checked the iPhone X myself so far.
