Morphology
The adjective 'dwarf' clearly signals small size and composes naturally with a following animal name, so the overall sense 'a very small ... whale' is partly derivable. However, understanding full reference requires knowing 'sperm whale' is a conventional species name (the 'sperm' element is not the literal biological cell), so the compound is not wholly predictable from its parts. Because the size meaning is transparent but the taxonomic name is lexicalized, this is best judged semi-transparent.
Etymology
The name dwarf sperm whale joins dwarf (very small) and sperm whale (a type of whale). So, it literally names a much smaller relative of the sperm whale, which is why it means 'a very small sperm whale'.
