It is possible to change the Gramps theme on the Windows AIO.
One choice that provides a pretty good looking dark theme is https://www.gnome-look.org/p/1206053/ the "OlliFri Gtk 3.18 Dark Blue Gradient".
when you start Gramps, your console may show some "Gtk-WARNING **: Theme parsing error" messages. These are usually harmless, but if there are a lot, and your Gramps screen doesn't look right, then your theme may not be compatible with the version of Gtk Gramps AIO is using.
You can check the Gramps Gtk version by starting Gramps from the console;
gtk++ : 3.18.9
