I read in bed on a Kindle and have found that lower brightness is helpful in calming before bed, regardless of whether I have the warmth up or down. The "dark mode" feature that inverts the screen I have actually have pretty poor experience with - I find it harder to read the words which leads to more straining which is counter productive. The only "benefit" I see of this feature is to decrease the overall light in the room which might be helpful for others sharing the bed etc.
