If a photon does not experience time then I find it challenging to imagine that it could have a perspective at all.

It gets worse. Not only do photons not experience time, they don't experience space either. From a photon's point of view, it's always every "where" it needs to be. Which means there's no distinction between places. Which means space doesn't exist, from a photon's POV.
Reminds me of this quote "A wizard is never late, nor is he early, he arrives precisely when he means to"
I once read somewhere that if you swap time in spacetime with gravity, then the universe turns crystalline, and lots of stuff makes more sense.

In that way, perhaps photons experience other stuff.
