Note that we applied the tone-mapping operator to the original rendered image, but not to the blurred bright-pass filter image. One could choose to apply the TMO to the blurred image as well, but in practice, it is often not necessary. We should keep in mind that the bloom effect can also be visually distracting if it is overused. A little goes a long way.
