What normal customer takes pictures of things in the dining room of any restaurant? That just screams “mystery shopper” and I don’t reveal myself. Ever. The rusted toaster oven and cardboard-wrapped table were on top of a seemingly otherwise-normal table in the dining area outside the kitchen prep area.
Sorry, but this is on you since the toaster oven and cardboard-wrapped table were in the dining area. It doesn't seem like this is a difficult picture to take. You were obligated to take a picture of this. How did you get a picture of the menu board which is located behind the register and above the employees' heads if you are concerned about being outed? Same question about the interior pic the survey asked for.
Behavior that you believe "screams mystery shopper" is different from what the guidelines state "never reveal yourself as a mystery shopper" which would mean in part don't go to Firehouse Subs and scream "I am the mystery shopper." I believe you when you say this isn't your first rodeo, but your actions suggest otherwise.
To answer your original question. All you can do is wait to hear back about your appeal, but I wouldn't expect anything from them. Appeals typically go in a black hole. They don't have a great appeal process since they don't send you an email confirming receipt of the appeal, when you should hear back by, and what should you do if the deadline date passes. It is not worth pursuing further.
As @jgardn02 noted, if you cite exceptions to the standard in the evaluation, expect to provide pictures backing up your claim.
