update:
I changed color theme because I was looking for a better one because of the change and then changed it back to what it was before to compare, and guess what? they are flipped again, this time it's the right way, darker in dark mode and brighter with dark mode off (as it is supposed to be, opposite to what it was after the update)
TL;DR
so, if you notice your themed icons in dark mode are too bright to be in dark mode, change color and then select it again and it's gonna be fixed.
