In game design what artists do is more than just graphics. There are minute details in characters that effect the story amd what ai overlay dont know have importance. Like scars or whenether the character uses makeup or colours their hair or something. These are storybeats and i dont really care if people want to see them or not. Some people skip the dialogue and its their decition.

Then the graphic artists and level designers work together with enviromental clues like is that wall climpable, or is that obstacle breakable. Also level design has often designed breadcrumbs like lights flickerin on a door or paint/blood splashes with vibrant colours to show where to go. If the ai starts to change these things they might become hard to see or overly bright wich in turn makes the game worse and player does not necessarily even know why it feels bad.

Maybe the right word is that something that sees only 2d render of the game and enchances it just how they see best at the moment lacks the undertstanding of the artistic intent.
