Does the Cosmos article accurately depict photon shape and wave functions?

[Ephemerality]

I came across this article on the shape of a photon https://cosmosmagazine.com/physics/what-shape-is-a-photon

However, the first image confused me, is it showing the wave function? Most other questions regarding what a photon "looks" like seemed to dismiss the question.

is it showing the wave function?

Not all of it, just its phase, according to the actual paper, which is on arxiv.org here:
