Looking from my own experience so many photographers are available it is hard to determine who may or may not be credible. Having a tv show connection provides that extra confidence that the photos will turn out well. It is one of those moments you can't do over.

But if the portfolio wasn't as high quality as others the tv connection wouldn't matter.

I would pay a little more to reduce risk.

And the biggest draw is brand. I might not have heard of you if not for your connection to the show. This gives you free worldwide branding. You could setup an online store and sell products or sell advice as a side business.
