Morphology
spherical + cow
The literal meanings of 'spherical' (ball-shaped) and 'cow' (farm animal) do not by themselves indicate the technical, humorous idea of an intentionally over‑simplified scientific model. Understanding this phrase requires cultural/disciplinary knowledge (the scientist's joke 'assume a spherical cow') rather than straightforward composition, so a B1 learner who only knows the constituent words would very likely not infer the intended meaning.
Etymology
The idiom spherical cow comes from a scientist's joke: to make hard problems easy, someone would say 'assume a spherical cow' and imagine a cow as a perfect ball. That's why the phrase now means a model or idea that is too simple and not like real life.
