DxO states engeneering dynamic range, which is when signal is equal to noise. Photographic dynamic range starts 3 to 4 stops higher. That is, if DxO number is 14, photographically for normal size prints 10 stops would be more or less realistic. However the last 2 stops will be damaged by flare, exhibiting skewed white balance and poor contrast. That is why we have 8 stops at default. Still, on low ISO 10 to 11 stops are workable if the camera and the lens are high end.
