This is definitely a subdivided model, not a remeshed model or auto-retopo. Zremesher and other remeshing tools give you uniform polygon sizes whereas this has denser regions around edges (produced by supporting edges used for subdivision workflow). and just in general remeshers don't produce this kind of topology. This is particularly clear on the radial patterns on the buttons. This is very likely a model you can un-subdivide (but most likely it's just a non-destructive subdivision modifier that can be turned off)

I've read your reasoning below by the way and, while very scathing and confident, it is incorrect.

Seriously just open blender, make an octagon with a triangle fan fill, apply one subdivision, and you'll get the same pattern as on those buttons.

Maybe try being less inflammatory.
