Update 1903 has messed up the 'Eye Care mode' on my Thinkpad X1 (5th gen) notebook.
I can select the toggle for Eye Care mode in Lenovo Vantage however it does nothing. I can also move the slider to a custom temperature, eg 4500k which is used in eye care mode however again this does nothing. Thanks Microsoft
