Since I didn't want to clutter the bug report thread, due to its rules and limits, and since other people might have experienced this judging by the fact that there is a similar bug report in there, I wanted to make an extra thread to mention something extra that I noticed.
I know that there's also been people who have had Armory Crate disappear entirely from the Dynamic Lighting settings, but this is different - for me Armory Crate is there, and it's the first in the list, and yet Armory Crate still gives control to Dynamic Lighting.
Now, I believe that this might be related to the ASUS AURA SYNC lighting service. If after a reboot, Armory Crate seems to have given control back to Dynamic Lighting, restarting the service in question fixes the issue. So might it be just the serving bugging itself as the computer boots up, perhaps falsely believing that Dynamic Lighting should have the priority?
