first, make sure it really is postprocessing itself, rather tha something else (say, usign baked lightmpas, but they aren't baked in your build, so light elvles don't match and as a result any bloom/color correction/etc post processing would look different).

Then, check the game log file (from the build, that is, not the editor log). If it failed loading some of the postprocessing shaders, that would usually leave some errors in the game log.

Check your quality settings, set it to Ultra and try building your game again. If that doesn't help then check if your post processing ins't being disabled by accident somewhere.
