Yes, it is true, I checked and after the movie Where's Gary got a 9, and after that Krusty towers/Mrs. Puff You'Re fired got a 9, and no episode got a nine until Sand Castles in the Sand, which as 9.2, then lots of Season 7 episodes currently have a 9 or higher (Single Cell Anniversary, Square Roots, I Heart Dancing, No Hat For Pat/Goo Goo Gas (I know its a season 5 eppie and a season 6 one, but in this list is Season 7 so), A Pal For Gary & Keep BB Beautiful, Gary in Love/Rodeo Daze, Back To The Past/Bad Guy Club 4 Villians, Day Without Tears, Squidward in Clarinetland, One Coarse Meal, Play's The Thing, Neptune's Party (even though it didn't air yet), Yours, Mine & Mine, Kracked Krabs, and a TBA eppie)
Look like SB is getting its spark back
