So just installed the October Update and was looking forward to the new dark Explorer theme, but sadly it is still very much white for me.
(Personalization > Colors and selected the “choose your app mode” option to dark).
Checked that the update has successfully installed. Tried setting to Light, rebooting, and selecting Dark and rebooting. All the screens that worked with the previous dark theme are still dark (i.e. all the System Settings/Control Panel screens). It's just Explorer that is steadfastly remaining very much white regardless of color setting.
