Unrelated note, there is a weird bug with videos on Amethyst (only sometimes, notably from jb55... So maybe iPhone videos cause this.. but not exclusively, perhaps a format etc)
What happens is the 'night light' setting is somehow disabled while these videos are on-screen in the feed. Specifically the entire kind-01 event containing the video causes it.
I tried to screen record it but ironically can't capture that because it's a hardware setting..
