Not sure about the color filter thing, but I can schedule Night Shift under Settings —> Display & Brightness. Manually set it for a specific time or schedule it to adjust automatically at sunrise and sunset.

I turn it on myself lol hit the lock button on an iPhone 3x

Shortcuts app. Create an automation that triggers based on time. You can even choose sunset and sunrise. Are you not using automations yet?

Android: Twilight -> Always. Flux -> Adjust colors together. Slide them all to the left, then bring the top (daytime) to the right a little. You want to filter the blue light all the time. Basically cut your exposure to any artificial source of blue light to as near to zero, all the time. This is true for lighting in your home, too.
