Short answer is that it definitely seems to be the requiem arrow, and in the recent anime depiction only one of the arrows has a design anything like that. Pucci's Stands aren't requiem Stands literally speaking, because they don't have requiem in their names.

Everything else is my opinion, but I'd say that stabbing yourself with an arrow is different from Stabbing your Stand with an arrow, so the first state of a Stand is never requiem because requiem itself feels like a Stand evolving, along the lines of Bites the Dust, so for Whitesnake to be requiem you'd have to stab it again.

Requiem is described as 'power over souls' though, and that's kind of what Whitesnake has.
