I just checked their website. They look like a very nice, legit business. You should either call them and ask if you could send them a picture for identification or just email them a picture of your orchid, explain that the tag must have gotten mixed up at Lowes, and ask them if they have any idea what your Cattleya might be. The nicer your are, the more likely that they will respond to your inquiry. It might take a few days as they do wholesale and it is quite a large business.
Here is the contact info:

Another interesting thought...it might be the right orchid but much redder when blooming during cooler temperatures. If the orchid was kept warm while the bud was developing, it might just be lacking the red pigment. I have had this happen with Cattleyas as well as other orchids. No idea. I would need to spend more time studying the photos.
