LG C1 OLED visually match white from reference

As usual all OLEDs shows a picture with an Blueish Greenish tint in them.
To correct it you need to visually match white from a display that you know have correct whites such as an calibrated Plasma or CRT tv.
Those are the only tvs without metameric issues and such reference for whitebalance still today.

This new 500A (50 hours running hours) is calibrated from an profiled i1D3 meter with an error of dE0.8 for white so its close to correct.

The C1 OLED have the ISF Expert Dark setting at 120 Nits and Gamma 2.2 here
Exactly the same as the KURO.
important that both tvs must have the same peakbrightness for this to work.

i could see right away that white on the C1 had too much Blue and Green in it.
i reduced Blue first the Green until white looked like the Kuro white.
when finished the white window looked really close to white on the 500A.
But this new whitebalance that looks correct on a test window will change on real content.
i explain why later.

i will still say that white and light quality on the C1 is slight better than on the C9 i had before.
its not usual that whites on an OLED looks correct on video like it does here.
it normally still has some blue tint to it in video and less when you look at it live with your eyes.

If you are an C1 owner and want an more correct whitebalance and brightness for darkroom,just change picture settings to ISF Expert Dark.
(First turn OFF energy saving which is ON standard )

Set OLED pixel brightness to 38 (equal to 120 Nits)
Gamma to 2.2

Change 2 point High whitebalance to this.
RED: 0
GREEN: -6
BLUE: -8

colors will also be better when whitebalance is more correct now.
