https://bugzilla.kernel.org/show_bug.cgi?id=218901 --- Comment #46 from Matan Ziv-Av (matan@xxxxxxxxxxx) --- I will look at the code later, but regarding the reader mode: In models after 2017 (I am not sure about the exact years) reader mode only controls the reader mode led. The firmware does not change the color temperature, as it does in 2017 and older models. I guess that whatever changes pressing FN-F9 happen in windows are done by installed LG software. -- You may reply to this email to add a comment.
