Mark, I think you might be missing my point.
What I am saying is this.
The viewer should perceive no difference in brightness between a 2D version of a movie watched without glasses, and a 3D version of the same movie watched with glasses on. The 3D version should be presented with a higher level of overall brightness hitting the screen than the 2D version (whether that is something that is adjusted in the creation of the digital master, or on the display device), so that when viewed properly with 3D glasses on, it appears the same.
If something is dim or difficult to see in the 2D version, then it should remain so in the 3D version. But it should not be the experience of viewers that a film is bright and visible in 2D, but dim and hard to make out in 3D. And if that is happening, that means that there is a technical problem in how the film is being presented.
According to this article, 3D theatrical presentations do suffer lower brightness levels compared to 2D:

Does the same thing happen with home TVs? In my experience it does, and my TV is calibrated. No matter how bright the 3D picture, the TV is capable of making the 2D picture brighter. That's an inescapable fact.
