Yeah, it's all a question of if you have the time, resources, and most importantly a good sample. Testing 41 shades only sounds bad because we typically have far too many design variables relative to the population of users. In those cases, we need someone with a priori knowledge of good design to limit the space we explore. When you can make billions of observations, you can start exploring experimentally much more of the design space.
