when I cut'n'paste the above in a file and render it all defaults (here 4/3, ie
960x720), the sphere's round.  if I insert 'right x * (16/9)' in the camera, and
render with '+w960 +h540', the sphere's round.

if you do not want to modify the camera, you'll have to stick with the (default)
4/3 aspect to see the shape you expect.
