In my experience backlit screens contain a lot of blue. I have been able remove the waking effect of my screen entirely using a heavy red filter provided by f.lux. But with the default settings, and even Apple's night shift implementation it's very blue. It is slightly less bad on newer devices that support "TrueTone".
