I don’t subscribe to Premium, so I can’t vouch for whether the enhanced bitrate makes much of a difference. But YouTube says that the improved video quality is turned on automatically “based on your connection and viewing settings,” so if you pay for Premium and your videos now look a little bit nicer, that might be why.
YouTube also detailed a few other improvements that are now available to Premium subscribers. You can now pick up videos where you left off when watching on smart TVs…
