Only a very small minority of users actually care about dark mode. It is not a general expectation for software, as loud as those users may be on forums like this one.
>Dark mode is used by 81.9% of 2,500 Android users on their phones, in apps, and in other situations. 9.9% alternate between the light and dark
So it's the other way around. Only a very small minority of users actually care about light mode.
If you're building win32 you're not targeting android.
I would be astounded if a majority of general Android users used dark mode, as light mode is the default on most phones (all, IME).
