Extra info:

My iPhone is using dark mode and I have the blue light filter on roughly half.

My kindle is an old model e-ink with no light.

    Since your Kindle doesn’t have a backlight (and especially the warm light), any difference really depends on the other lighting you are using. A dim, warm house lamp is probably better for sleep hygiene than the phone even with it changing its color temperature. If you have no problem falling asleep with either one then I don’t think it matters much.
