So reinstalling Skyrim from scratch made no difference, but completely reinstalling Vorpx did.
Although it does seem a little zoomed in to my eyes, it is at the correct FOV now as disabling Direct VR doesn’t change the FOV and typing “Fov 110” in console has no change whether Direct VR mode or not. In other words, the FOV appears to be correct now.
Thank you for your assistance.
Interesting thing to note here is that returning Vorpx to factory default through the program did not fix this issue but actually reinstalling the program did.
