The lighting is exactly the same in the V-Ray and Corona versions. In fact, to me at least, the images look extremely similar with the exceptions of some of the materials that had to be rebuilt from scratch. EDIT: Actually, now that you mention it, the HDRI might have a slightly higher intensity in V-Ray, and the Eucalyptus leaves seem to catch the light better there. This may have to do with a slight difference in the map's orientation.
The Octane version is a different ball game altogether because the renderer just has such a different philosophy. Everything, lighting and shaders, had to be rebuilt from scratch there so the result was bound to be very different.
