Dark mode in certain apps not really dark
i enabled dark mode with 90hz refresh rate, Splendid Natural setting. the dark area in certain apps (gboard keyboard, WhatsApp, chrome etc) appeared as dark blue. and the brightness at that area kinda high and makes it kinda grey-ish. it also effect the video quality. when i play vid on YouTube the picture quality kinda bad. the quality is lower than my OnePlus 7 (optic amoled panel). does anyone have a same problem? is this a software problem or only my phone act like this? is there any setting that i should change?
