It gives the mastery you'd have gotten by doing all the nodes of the planet on the previous starchart.

That's why there's no difference, if you've already done all nodes before the update, you don't get any mastery because they didn't add any in total.

The starchart still gives the same amount as before, but it's spread differently now.
