Who says programmers are responsible for pixel perfection? That's what the graphic artist do. But I get your point of thinking former game developers would be too exacting. That is what hiring filters and management is for, so you hire with reason and guide them to the company's level of production quality. Also, the typical game is significantly larger than any single gamer experiences, and game developers certainly know the tradeoff of "good enough". Plus game production environment is a technological feat in itself too, and it is those type of game developers that contain the most value - not necessarily the game play developers, but the game production pipeline developers.
