The answer is: it depends. They will silently bend the "TRC" a little if there is a business case for releasing something now and not later.
But most of the requirements center around nitpicks of software polish: Specific words and phrases used to discuss the device, loading screens must not just be a black screen, the game should not crash if the user mashes the optical eject button, etc. These things add a level of consistency but aren't the same as "solid 60hz" or "no input lag". The latter sort of issues can be shipped most of the time, they just impact the experience everywhere.
