To anyone who has examined the soundtrack on Vinyl I was wondering if you were able to see whether or not any information existed beyond 22.05kHz. through a spectral analysis?

Just consider yourself really lucky to own a copy of that on vinyl.
I only wish . . .

I really like that music score.

If I can ask (and I really am interested), why the curiosity to see if there's audio information above 22.05kHz on this particular vinyl LP?
It might all ready be known in these circles, but, depending on the cartridge/phono-preamp setup, you won't find “stable” reproduction at those high frequencies (I own a VanDenHul that will reproduce 22kHz, but I'm not so sure my phono preamp will—nor my ears). Beyond the usual considerations of the quality of the vinyl it's pressed on, the other thing to consider is the vinyl mastering. Nowadays, with very little exception, mastering engineers roll-off the high frequencies at 16kHz on a steep slope as they cut lacquer masters (especially when most sources are very hot 24-bit 96kHz masters). High frequencies produce massive amounts of heat in Neumann cutter heads and since they're impossible to repair or replace if they blow out, everybody severely attenuates those high frequencies to protect their irreplaceable (much in-demand) cutting lathes.
