My Question or Issue

In Australia, just switched to Spotify Premium from Free and use Bose Soundlink Revolve plus.  While playing a song, no sound quality difference when I toggle through Automatic, Low, Normal, High, and Very High on my iPad or iPhone.  No difference either when running on Windows 10 PC, except (as expected) there is no Low choice.  Anyone any ideas on what to do?  Thanks very much.
