I can’t remember where but I concur that the PK used in Imperial Majesty is in fact the Suge Pure Kush. That’s why I snagged a pack also. I’ll do some digging today.
Edit after some digging : my best guess after some breedbay searches is that Bodhi for some reason took the “Suge” moniker off the cut and just started naming it Pure Kush or Pure OG in his notes.

The above link shows the last time I can find him mentioning pure Kush suge. After that it’s just Pure OG or Pure Kush. All the same imo
