That is an eye-catcher. There are very many different smaller hybrid Cattleyas that are yellow with red splashes on the petals. It wouldn't be possible to give it an ID without the label. There are breeders in the US, Thailand, Japan and Taiwan breeding Cattleyas like this.
You could try to contact the place you bought it and ask whether they know. Or perhaps they could tell you where they bought it, and you could ask the grower.

Any guess as to ID is going to be just a guess.. with only a few very distinctive exceptions, it is impossible to definitively identify a hybrid, especially a complex one ... as ES pointed out, too many look similar. The best you're likely to get is "Looks like" or "Similar to" ... just enjoy, it is a beauty.
