Can't find anything about this Paph Kerchoveanum (curtisii x barbatum 'Wide spread')

[Surrealle]

Hi all! New here and newly interested in orchids. I went to a sale at our local botanical garden in Omaha last weekend and picked up a phal (which I do have a few of already) and another one that I later learned is a paph. Cue a flurry of online searches to try to figure out how not to kill it, since evidently there's different kinds with wildly different ideal care.

I'm guessing this is a mottled leaf type which appears to do better with hard alkaline water (we have well water) but we also have an RO system which I could use & add ferts to. Any suggestion which way I should go?

I'm normally a bit of a brown thumb but I'm trying to get better at it and didn't realize I was jumping into the deep end with this one, but I just really liked the leaf pattern.

TIA for any advice & tips!
