I compare your CIE coordinate  with this website [ https://www.ledtuning.nl/en/cie-convertor ]
it’s different, And i use coordinate from this link ,result is better than your coodinate. but not correct at all.

i find wp 6500k of my notebook [panel n14bge-l42] by calibrate many time, and i found coodinate that can make my notebook correct at 6500k is “x=0.3135 y=0.3236” ( I compare it with my calibrated LG 24MP68VQ-P 6500k [98%sRGB] )  ( use Spyder4 )

Why 6500k result can make from “x=0.3135 y=0.3236” ? ( this value near 7100k [pink color shift])

Because of Colorimeter? Aryll? Display? or Algorithm?

  1. I compare your CIE coordinate with this website [ https://www.ledtuning.nl/en/cie-convertor ]
    it’s different,

    They are using the planckian (black body) instead of daylight locus. This is a choice as well in DisplayCAL.

    Why 6500k result can make from “x=0.3135 y=0.3236”

    Colorimeters “see” colors via their sensors with color filters in front of them. The better a colorimeter’s spectral sensitivity matches the CIE 1931 2° standard observer, the more accurate it is. The Spyders are not great in that regard.
