It varies with use case, but on ethanol, you definitely want to get the injectors cleaned. Looks like OP's injector's were in pretty good shape.
DI injectors are more important to clean than PI, as the DI is what is used for fine fueling requirements.
Not all fuel injector cleaning services can do DI.
