From my limited access to the profile it's pics of off.  But cannot tell if that means some would be really dissatisfied or if it just means a different looking girl. I would guess that she is a "if you only want performance and don't care about anything else" type option.

Ad is NOT accurate looks wise. Some mongers I keep in close touch said it's her right away by looking at the face, so I guess face may be somewhat close, but not really.  

 
If anything, I think Yuna herself is worried about the ad not being truthful and old regulars not being sure if its her...and those who never tried her thinking its a new girl. Also ad said she has natural bs, which is just not true. She has rock hard implants that arent that well made.  

I wish she used the old pics on the ad, this ad is misleading.

 
But yes, its all about service., She easily takes the title of best available DT in the bay. Back in her prime she'd also do what I call death by snu snu. Violent jackhammer ACG action for 10-15 minutes with perfect rhythm.
