Yes, all Babl objects are effectively singletons - and the same
internal object will be returned for all subsequent calls that refer
to one.

This depends on what you are trying to do, if all you are trying to do
is to avoid creating multiple fishes referring to the same two formats
than babl already does this for you internally. Just like pixel
formats and types, you should be getting the same fish, with
significantly less computation needed. On subsequent requests.
