On both the engine and the transmission. Apparently, according to the previous owner had a 98 tune, but on the fuel door it only says Premium Fuel Only, on a aftermarket sticker. Without trying to get onto the original seller, is there any way to find out whether it might be 95/98 compatible, or only 98? Such as using a scan tool possibly, not sure if it’s something that would be identifying within. at this point I don’t want to just dump 95 in it and hope for the best - but hoping there’s a way to find out on my own before chasing up previous owners and tuners.

If you run a lower octane you are a chance of it running into detonation scenario's under high load. Once it's tuned, you can remove and/or ignore the sticker on the fuel door.
