Outlook ignores Darkmode images on HTML

I’m creating a signature in Outlook for Windows (latest build as I write this) and my signature is not working great in dark mode, so I changed the HTML to use different images if the user is in Dark Mode:

    media="(prefers-color-scheme: dark)">
   <img src="https://superuser.com/DarkMode_files/image002.png">

This strategy works perfectly in Chrome as I debugged this already. However in Outlook it always uses the non-dark mode ignoring my dark mode settings.

I understand Outlook doesn’t support this yet?
Thanks for confirming.
