mine looked a lot like that when it was young, actually, a little more lacey/patterned.
The only time it was close to being that pale was at the store and once in my tank when scared, otherwise quite dark.
Now it looks like a normal O, mostly black, orange spots, and occasionally shows the lighter pattern underneath.
I would have to see a grown one to believe it was a different type ...
usually it is just a case of a seller changing the name to induce sales or hike rates (sometimes both).
Who knows though, if they are working on genetics and breeding new lines ... just about anything is possible I suppose.
Looks like the next time I am in the market for an Oscar, there might be some new colors to choose from (in 10-20 years

)
