The overture on the Varese LP is indeed the FULL version. The Phase Four recording is the full version. The Debney recording is the full version. The Paul Bateman recording on Silva Screen is the full version. The first track on CD1 of the Prometheus set is the full version. The last track on CD2 of the Prometheus set is the full version.
The edited version appears only on:
The Varese CD of the OST. The first track on CD2 of the Prometheus set.
Couldn't you add The Overture on the Colpx LP is the full version (mono)?
