I don't think it's helpful for anyone here to know the exact offset a LG 2017 OLED will need when you are using a Minolta CS-2000a to match a reference CRT D65, unless it's a Minolta user and don't have access to the same place he has his OLED to a Plasma or CRT to perform the same perceptual matching procedure.
This White Point offset can't be used from other meter users.
We can say the unit to unit variation between Minolta's are below +-0.001 xy and the agreement between Minolta with any other 5nm spectro (which is recently certified) can be max +-0.002xy.
The posted White Point from Tyler is x -0.0054 y -0.0076, It can be useful for example from users of 5nm spectro's, but since we know that i1PRO's are not coming with any certification about it's performance in Emissive Mode (Their NIST document confirms that is accurate for Reflectance Mode, for papers, printed photos etc.... nowhere the proof of performance in Emissive Mode...we use that mode for display measurements) and if we count the larger unit-to-unit variation these meters have, it's better for any i1PRO1/2 user to to just perform that kind of comparison (using a Plasma/CRT or CCFL-LCD) to his own place because using another people offset it doesn't guarantee better results.
In Reflectance mode, i1PRO is using it's internal tungsten lamp to illuminate the object (the color on printed paper...since you using the meter in contact mode to the paper, if the lamp will not light up, it will be like taking a dark reading), so after the llumination (which i1PRO has certification since they used about 25 colored ceramic tiles to test/pass the certification) the reflected light will be analyzed by the i1PRO. When you are measuring a display; since the display has it's own illumination; the meter is working in Emissive mode and internal lamp is not used.
There is a reason why i1PRO's are called as Spectrophotometers (they measure the spectral reflectance of an illuminated object) and all other reference spectro's (JETI/PhotoResearch/Minolta/Colorimetry Research called Spectroradiometers (they measure the spectral radiance of an emissive source.)
We can say that i1PRO is both Spectrophotometer (when it's working at it's reflectance mode) and spectroradiometer (when it's working at emmusive mode).
X-Rite is calling it spectrophotometer because it's missing some specifications to reach some standards/certifications to be a true spectroradiometer.
