I have to agree with Superku, the bloom overbrightens the image a lot.
It's caused by the blending mode of the bloom (additive-blending).
When using bloom you have to adjust it carefully to not mess up the final image.

...and if you have some experience with shaders I suggest you to stay as far away from additive-blending as possible
because there's nothing which creates more overexposure than this blending technique due to the limited color-range
which can be displayed.
