Do restaurants really serve reality TV food?

On watching another reality TV cooking show I do wonder if restaurants really serve sauce smeared across plates - cubes of vegetables so small they could not possibly taste of anything and food stacked so high you need a ladder to reach the top. What is wrong with serving a decent crumble, what does it have to have a twist? What is Jus that gravy or even sauce would not suffice? What is wrong with a plate of food why does food have to be sculptured?
