Yes not all meaningful interpretation of the Bible is necessarily what's classed as metaphor, some of it is "the moral of the story" etc. "The four interpretations" which is linked here sometimes has literal as one of them, but that simply means any metaphor is built on a literal story. People who live in glass houses has a literal interpretation. The emperor's new clothes has a literal interpretation. The pods in The Matrix has a literal interpretation. Etc.
