I don't know that the geometry *IS* different between electromagnetism and Gravity.
But I haven't been able to find a model as large as our Sun and Earth re: Gravity for the electromagnetism argument one way or the other.
You keep trying to put the burden of proving or disproving the analogy of Electromagnetism and Gravity on me, yet it is your argument, not mine, that they must be the same.
And you may very well be correct, but I see no reason why I should be compelled to show it one way or the other.

The theoretical motivation for my saying that they are the same under Newtonian physics goes all the way back to Coulomb. I'm trying to understand your theoretical motivation for saying that they're different, if that's what you're saying.

Because right now your version of physics isn't hanging together. Rescue it if you can. Either gravity and E&M are analogous in your model or they are not. If not, why not?
