I said "virtually perfect." If you wanted to compare the CMBR spectrum and a perfect black-body spectrum on a scale enough to show there's a difference, you'd need a piece of paper the size of a basketball court. At journal size, the error bars are smaller than the width of the line drawn. That's close enough to perfect for me. And the main point is that no one's shown a way for the steady-state to generate the same curve.
Everything I need to know I learned through Googling.
