Yeah, I was looking at youtube videos just some moments ago on how to care for orchids and stumbled upon one on a Brassia, which resembles mine more than the Olmec seems to. It had more slender petals and the same colours as mine, also on the lip. The lip, I think, was slightly wider than mine. Not sure which exact Brassia it was, however.
I'll contact the store where I bought it to try and get the contact info or name of the supplier and reach out to them.
