From what I understand, "pincushion" is a broad curvature of the geometry on the screen caused by an internal light engine/lens/mirror/screen relationship flaw. "Bowing" is a local curvature on the screen caused by the TV case twisting what is supposed to be a flat surface. In my case, pincushion is imperceptible, but I originally had an upwards curvature in the lower left corner of the screen. This was temporarily cured by a thin shim; long term I plan to place the TV on a sturdy, flat stand and ensure that it is level, instead of using my current cheap fiberboard stand.
