Photorealistic: yes. However, it could be debatable whether it’s gruesome. We see situations that characters survive with short term damage but no long term consequences (example: Homer skating into the canyon). So while it would be gruesome to us, it’s probably closer to slapstick to them.
The other characters are quite perplexed about the idea of 3D, too.
Anyway, that answers the good old question “Is the gruesome cartoon Itchy & Scratchy photorealistic from the Simpson’s POV?”

I never thought about its gruesomness this way.
It would be abhorrent for us to see photorealistic cat organs but I guess kids in The Simpsons’ universe are raised differently.
