A particular class of quantum observable discrimination tasks, which are equivalent to identifying the outcome label associations of unlabeled observables, was introduced in [Physical Review A 109, 052415 (2024)]. In that work, the tasks were investigated within the "single-shot" regime, where a single implementation of the given measurement devices is available. In this work, we explore these tasks for non-binary observables as well as within the multiple-shot scenario, where we have access to finitely many implementations.
