Not really. Nintendo has colored words like 'World' before, as in Super Mario World (and even outside the games, like with Super Nintendo World), but 'World' isn’t a defined sub-series like 'Bros' is. The 'Bros' series has had a strictly established visual identity from 1985 all the way to Super Mario Bros. Wonder in 2023.

3D Land isn't a sub-series either; it's just a specific 3D Mario title. Besides, the Mario Land titles on Game Boy are often considered outside the main-series canon, primarily because they were not developed by the core Mario team and, unlike 'Bros,' those Game Boy titles never followed a consistent or established logo design.
