Sentiny This is on MBP mini-led so not exactly the same, but I usually have to tweak a bit in BetterDisplay.
- Use 100% resolution so it matches the native one at 2x for retina. At least until things look stable.
- Disable colortable adjustments entirely, and enable the ones that use Metal.
- Force color profile sRGB in chrome://flags
- Open some webpage with a white background and adjust the color adjustments until text seems to be part of the white background, including the color sliders.
For me finding some combo where it seems as flat as possible feels more important than killing off the last flicker. But tbh I don't know any more, as I suddenly feel that my iPhone OLED doesn't strain with reduced white point 100% and 100% green/red color filter that kills off any bright red.
