System Information
Operating system: Windows 11 Home
Graphics card: NVIDIA GeForce RTX 3060

Blender Version
Currently in Blender 3.6.2, hash e53e55951e. Don't know of a previous version where this worked.

Short description of error
bpy.ops.image.clipboard_copy() doesn't respect the color management render panel when copying renders.

Exact steps for others to reproduce the error
Using the startup file with the default cube:

  • in Render properties -> Color Management, change the exposure to something ridiculous (I used 10)
  • render
  • in the Image editor menu, select "Image" -> "Copy"
  • paste into any image editor

This is a screenshot from Blender:

This is the copy operator's result in the clipboard, pasted into Window's Paint:

I believe the color management option in blender is basically transforming for display, the data is not altered. But would like to hear more explanations from the devs.

True, the display's version isn't representing the original render's data. The reason I mention it is that when the user does Image -> "Save as..." on a render, the default settings include color management, which defaults to "Follow Scene" for exposure, view look, gamma, etc.

So if users want to copy the original image vs the display's rendition, it'd be nice to at least differentiate them somehow.

Still seeing this in 4.1
