Why there's not Linux? At least you can determine light/dark theme by quering GTK theme name. Every GTK theme mentions whether it's dark or not in it's name.

Right, dark/light seems to be possible on Linux, I missed that

There is now an official system theme for dark/light preference in Linux being adopted by couple Desktop Environments

Resources:

• Provide a standard dark style preference key in the settings portal
• Elementary article
• Gnome 42 Dark Style Preference
• KDE implementation
• Elementary implementation
