It's definitely implied. Should I tag it even if it's not exactly visible?

Meh...

I don't think so. Unless you see it yourself, the rule is "tag what you see", not "tag what you think is happening".
But if the artist has said it is (whether in a reply to a comment on their original post, or in their description), then it should be perfectly fine to do so.
