Looks like nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 just uses the system setting (forget it was possible to set independently before or not).

Dude! You are so smart! System settings had mysteriously gotten switched to light mode. Now, my only issue is when I have this ridic robot avatar instead of my precious flappy-winged laser eyed bee. 
Sometimes profile settings don’t get published to ALL your relays. And luck of the draw Damus gets the profile image from the relay where it is missing. I have this frequently when updating my Lightning address and still get zaps to a wallet address no longer (apparently) in my profile. Resolution is to reset your profile image again, save it, and hope all the relays are behaving.
