Team Eteri swept the individual Grand Prix events and then swept the podium at the Grand Prix Final.

The only other Grand Prix Final sweep I see on Wikipedia was the men in the 1998 Grand Prix Final: Alexei Yagudin, Alexei Urmanov, Evgeni Plushenko
They had all been coached by Alexei Michin... but Yagudin left Michin for Tarasova after the 1998 Worlds and before the 1998 Grand Prix Final.
Eteri gained almost exactly 20K instagram followers during the Grand Prix season.
