I read this a few times and still didn't understand your point about your friends TV settings and what a fantasy game like destiny has to do with fh2 and drive club.
He was used to unsaturated settings where the world in his TV has less colour than even real life, and everything had a warm gritty look to it, even Destiny.

If they are used to looking at non-saturated or washed out pictures etc. then that's the only way I can understand if someone said Forza 2 looks cartoony.
