Isn't the term "well endowed" obscene?

I wouldn't say that. I think it's more of a euphemism. 

I'm told "meant to be seen" ;)

sounds like it

Not if the reference is to someone who has a lot of money. :)

Does depend on context - certainly not obscene if meaning rich, as SpunkySenior points out.

In the erotic sense it is a slightly risqué euphemism, and any obscenity really lies in the rest of the text or speech.
