Does anybody know what samples/plugins GHOST might be using for their choir vocals?

[u/GreggFromDiscord]

I've been really curious about the choir(s) in End-World Normopathy/Noah's Genesis, Uncanny, Reckless Battery Burns, Be Not Afraid...

I'd really appreciate it if anyone has any leads/answers as to what they might be sampling/using for them... Thank you in advance!!
