The major problem with "night mode" probably is that it's by no means standardized.
What you did not talk about is the ambient light:
Do you edit in complete darkness?
If so, the color temperature of your display "white" would adjust your visual system to white (within limits).
However if you have an ambient light, the whole situation is much more complicated:
Ambient light also infuences the "white point" if it's relatively strong.

You basic problem is: Your images will look the same only under the same viewing conditions, that is: Same device, same mode, same ambient light.

Easiest solution: Realize that it was a bad idea to adjust the photos in that way and then share them.
