> I wonder if it would be possible to put the camera shutter and the oled out of phase enough to substantially dim it.

That is exactly the idea, to sync the camera to capture in between OLED pulses. It's not going to be perfect, but then to use computational photography to subtract whatever bleed of pixel color is left.

In theory, it should be totally workable. In practice, I'm not sure what the tradeoffs are in terms of acceptable image quality and resolution for the camera.
