WYSIWYG - yes it’s that bright. 

Yes this is the real deal. 

 It is super cheap because it has all green/yellow. That seems to be the dominant color. I do have them with red but they are much more expensive. I have had people message me with red developing in theirs a few months after purchase and some have said it has not yet developed. I would say it is a risk and if that is super important then consider one of mine with red.
Here is a thread that might be worth checking out from others that have experience with all green/yellow.
I will say this though even without the red it's a beautiful Coral.
