In reality, the earth is actually not flat, spherical, ovular or ellipsoidal. It is what it is, the geoid. An irregular shape that some people spend their careers trying to measure as accurately as possible which in turn has an impact on a wide range of applications.

Its more of a similitude. Obviously scientists will continue to evolve their nomenclature based on their most accurate data.
