I really don't get this obsession with "bloom", or what it is. If I want more bloom, I'll put a live flashbang on top of my monitor.
Go outside in the Summer about 6 to 7 am. Turn the water sprinkler on.
As the sun comes up and the rays hit the water you will get this special glow you only get when the sun is low in the sky.
(ADDED) Also when a bright flashlight or car light first hits your eyes and everything blooms out real bright until your eyes adjust.
That to me is bloom. A lot of games overuse bloom to make things look all glowy.
Personally, there's a time and place for it, but not all the time.
