It fits with my understanding as well, but comes from investment grade bond ratings where AAA usually signifies the highest quality (i.e. the best chance of getting paid back). A AA bond is still a good bond, but it has a higher risk of default.
But in practice, I just see AAA as a “high budget production,” both in development costs and marketing. It doesn’t mean it’s a better product, just one with a lot more money on the line.
