It doesn't meet a perfect theoretical definition of net neutrality, but it's a set of defined legal limits on the extent to which providers can treat different kinds of traffic differently.

Net neutrality is not theoretical, not some unattainable platonic ideal we can only hope to strive for, it is literally the default setting.

Any deviation from that default requires special effort be taken to monitor and identify network traffic, and as soon as you have expended that effort you cannot truthfully claim to have net neutrality.

Ok but the main limit people care about is music and video streaming being treated differently
