A couple of tips for your next search. First of all, congratulations on your first session and review. Nice review, by the way.
Now, when you look at a profile with 10 pages of reviews, you want to look back and see the dates of the first reviews. In Samantha's case, she was first reviewed in 2002. This is important because, at TER, the profile is not automatically updated by subsequent reviews unless the provider turns out to be a ripoff.
Once created, Profile information can only be updated by the provider upon request (except contact information through the Problem Report System). So, in this case, Samantha, herself, would have had to request that the fields about photos be updated, and the chances of that are not very good.
So, as you said in your review, her pictures are about 8 years old, which is in keeping for them being accurate when wokf reviewed her in September, 2002. And even then, he gave her a 7 in looks.
Also, when looking over all 10 pages, she received roughly 60% scores of 6's or 7's. That should tell you a lot. On her top page, she received 7 7's and two 8's. The difference between a 6, which you gave her, and a 7, which she usually receives is, IMHO, pretty much a toss up.
So some learning points could be that you look at the whole review history, understand that profile information, once created, is mostly controlled by the provider, and account for time changing some things that the provider may not want to change on the profile, particularly with regards to appearance.
Overall, your experience is in keeping with her general review history. The performance scores and description matches what most others have written.
Good luck
