Do you say something if you think your opponents model is too much?

Look I totally get the ‘your model your paint scheme’ rule, after all it is your hobby and you don’t owe it to anyone but yourself.

However, recently I saw a bloodthirster model with a literal dick attached to it. While it was brilliantly made, I do feel a bit weird if I were to play against it. I have also played a guy using csm and put one of his rotten teeth on a model for aesthetic. He said it’s clean but honestly the condition of the teeth didn’t really look good.

My question is what would you do in these situations, would you say something? Or would you just let it slide?
