Custom color attribute vs. vertex color - difference in color managed render

Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-03-19 21:37, hash: rB3494946560c2

Short description of error
There is a mismatch while displaying the vertex color layer and vertex color set as a custom-attribute.

Exact steps for others to reproduce the error

  1. Run the script which sets the vertex color layer (Col) and custom attribute vertex color (GN-Col).
  2. Then change the max input of *Attribute Randomize*, it will update the colors.
  3. In shader nodes switch between two vertex colors: *Col* and *GN-Col*.

Event Timeline

I'm not sure I understand the problem correctly.
What view mode are you using?
If it is the Viewport Shading "Solid" mode, it is expected to the material nodes to have no effect.

I believe there is a difference in regards to color management between attributes and vertex colors.
I also believe we have the same difference between Vertex Colors and sculpt vertex colors.

Will confirm for now, would assume @Brecht Van Lommel (brecht) knows about this? [this might very well be intended behavior]
