Can anyone ID this paph?!

[Orchid grower]

Hi everyone!*

I recieved this lady slipper last July as a gift from my sister. She paid quite a bit of money for it but didnt get a name. Considering what she paid I'm assuming this must be some sort of species and have a name or so I'm hoping..*

It was in bloom when I recieved it from the larger plant and the second leaf growth was just beginning. The second growth got bigger and then spiked and has now bloomed.*

I dont even know how to take care of this thing and I've literally done nothing other than water it here and there.. so I would love some advice on how to care of this plant!

The media it came in didnt look that great but I havent repotted because I'm scared I'm going to kill it. I know nothing about paphs!*

Thank you!
