Yeah the anime has a tendency to give people free power ups in the middle of battles for usually BS reasons to extend the fights while the manga rarely does so until the end of the Goku Black arc. Examples being Goku's 10x Kaioken boost and Hit's adaptation ability that they introduced to match it, and Black getting powered up every time he's injured (in the manga he could only do so from severe injuries).
As for Vegeta, can't really think of any asspull boost besides SSJ2 Vegeta being magically mutliple times above SSJ3 Goku in the manga, and seemingly getting plot boosted during the final fight in the Black arc. The most egregious offenders of asspull power ups were Goku, Trunks and maybe Piccolo, Gohan and Freeza iirc. There's also Roshi getting godhaxed, but he's still only relevant to base Saiyans anyways
