Mold in Travertine?

A friend of mine has contacted me regarding the filled travertine (doesn't look polished) in her shower that has developed black spots. The spotting is primarily in the area of the shower spray. It was has been sealed twice, once at installation and once after about five years. I do not know what kind of waterproofing is behind the travertine. Scrubbing/cleaning the surface does not remove the spotting and it becomes more visible when the surface is wet. Is this mold and do you have any recommendations on how to get it out of the pores. See pics (yeah, I know they're bad.)

Mold generally is a moist (vs.wet) surface thing. It would scrub off, especially with something soapy or bleachy. That it’s mainly where the water spray is, is odd for mold. The constant wetness and pressure would make it not too conducive for mold to get a toehold (get it - floor of the shower - toehold. Ugh, dad joke).
It might me metal corrosion/rust due to microscopic particles within the tiles starting to oxidize in the water.
How does it do with the usual mold cleaning stuff (Concrobium, Tilex, etc)?
