Although I think I see where you're coming from—normally what's unavailable is "grayed out"— I prefer the eye icon when OFF to be bright. It attracts my attention so it's very easy to spot and avoid or turn on.
I use the Detail view almost all the time, btw. The off icon is big and bright and bold in the middle of the Compact view—impossible to miss whatever color they make that icon, but with the dark outline and white interior, it seems to show up well against any background.
Definitely agree about using the Detail View, Cristen. On desktop, the visible state has a bright icon (and no icon for the off) so it's hard for me to adjust to the reverse of what feels familiar haha.
