System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 445.87

Blender Version
Broken: version: 2.91.0 Alpha, branch: master, commit date: 2020-10-12 22:51, hash: dc71ad0624

Short description of error
I am aware that there was a somewhat recent bugfix to the way Eevee handles bloom + transparency (I couldn't find the commit, but I'll edit this post when I find it). In the latest experimental builds the problem seems to be fixed, however when I go to save the image the output is still broken, and looks the same as if I rendered it out of 2.90.

2.90 render (saved, and when in image editor)

2.91 render (saved with 'as render' checked)

2.91 render (saved with 'as render' not checked)
2-91_save_not_as_render.png

2.91 screenshot of the render in the image editor displaying correct behavior.

Exact steps for others to reproduce the error

  1. Add object with bright emissive material
  2. Turn on bloom
  3. Render
  4. Save image

Here's the test file I was using
test.blend

Always a bit on shaky ground when it comes to Color Management.

This might very well be the correct behavior, since you leave out "render part of the display transform" when saving.
Note we also have the View as Render option (which will apply the "render part of the display transform").

Just to make sure we have all required information: Are you saving EXRs? PNGs?
