I remember when I finally read about this whole color calibration thing about 15 years ago, I also felt WARM was a bit "too yellow".
It lasted for about 10 minutes then its obvious that its the REAL accurate color. Real life looks like that.
So yeah, for all of you doubting the Warm recommendations, just stick with it for like half an hour and it will make sense. Normal or Cold is just artificially blue, life is not like that, you are ruining the perfect quality/color rendition you would expect from any display, more-so a new OLED.
