The term jumping the shark stems from an episode of Happy Days. The show was ailing and loosing viewers and so they did a stunt where the cast went to Hawaii I believe and Fonzy while water skiing, jumped over a shark. It got a ton of ratings in a fast burst but then continued downhill.

So what it means is to do something flashy or showy to get attention to try to save something that's failing.

My response to the OP is...no, not even close.
