Maybe...
Cat 5 is 30,000-40,000 points, so basically a free night at this hotel. Fair in that respect.
But these days I'd rather have cash than HH points, so I'd ask for a refund. Mention the pictures you took and how they'll look in a Tripadvisor review.
Basically the decision, in my mind, is a fair amount of points offered vs cash. I don't think both would be fair.
