Who knows, which catteleya this is ???

Hello ladies and gentlemen.

This is my first post.
I thought I join the board to solve a puzzle that I have:

I bought the attached orchid almost two years ago and now it bloomed for the first time, letting me know, that it was not quite happy with the name it was given: it was wrongly labeled!
Does somebody know what the correct name of this orchid is?
Petals have magenta in them, whereas sepals have a portion of yellow, making them almost a little peach colored.
The flowers are 5.1'' wide, the plant is uni-foliate with 6'' pseudobulbs and 8'' leaves.

Thanks very much for your help,

Miyami
