I'd not thought much about it, but I think you're right.
However, Galadriel loses because of the Halloween scene...
The scene does come directly from JRRT's Frodo's encounter with Galadriel at the Mirror. The haughty Noldorian princess, related to but not controlled by Feanor, came to Middle Earth in the first place to set up her own kingdom and rule it to her pleasure--so that scene meant a lot when she suddenly became fragile, humbled and "diminished" after playing Lady Frankenstein. I think it works. "I'll remain Galadriel..."
