Correct.
But what I need is actually a height-SPHERE, so I'm back to plain mesh.

Well, in some way it IS. Because one could imagine an algorithm which 
uses less memory (at the expense of CPU time), but only for the 
specialized problem of a height sphere. 

But, I agree: The fact that a genuine mesh does not fit into RAM is 
not a POVRay bug because I see little chance to significantly reduce 
genuine mesh RAM consumption (after looking at the POV code).
