The issue affects Kinetic too. When you change the theme, it does immediately update the chromium snap but other apps (both snap and non-snap) seem unchanged. I tested a limited number of apps for the immediate theme change:
* chromium snap - theme updated immediately
* gnome calculator (both deb and snap) - theme updated in the snap immediately
* gnome tweaks (deb) - theme not updated
It seems like the theme of the snaps are being updated immediately via snapd-desktop-integration, but the debs are not being updated until a reboot.
