Exactly. Apps ignore anything but a “use dark mode yes or no” option, so the improvement was to add it. Tiny from windows perspective, huge for users (since the apps now actually respect it).

The difference to windows users is that you change a switch and apps actually change whereas before you couldn’t do that.

It wasn’t Microsoft’s fault before and it isn’t they who updated the apps now so they don’t get credit for that. But the fact remains you basically couldn’t use dark mode before and now you can.
