Cattleya gaskelliana var. albescens
 

This is a very clear rose flower, almost white. I have three leads on this plant, but only one flowered with just one flower. A second sheath has a bud inside, but it seems to have stopped growing.

Not a strong perfume, but yes it is perfumed Tindo.

The picture looks white with a slight pinkish blush, is that the true color? It has a nice delicate appearance...

That's it, that's the true color, Phantasm - a slight, delicate pink throughout the entire flower. Almost, but not white!
