This is an awesome hack, and it's a great way to fix behavior without having to collide with bureaucracy.
It's not ethically fraudulent because the shipper shouldn't be breaking anything. And I'm sure they do pay fees for what they break, and the shipping company is trying to do what it can fix that, but putting a picture of a TV on the box is still more effective than whatever the shipping company is trying.
I'm scared to think what else you would view as ethical fraud, if pictures-on-boxes qualifies. I tell baristas that I want "room for cream" in my Americano. But I never put cream in it--- I just want less volume so that when I walk I won't spill hot coffee on my hand. #EthicalFraud
