PNG Texture has lower quality when loaded during Runtime

Texture

-

How to reproduce:
1. Open the attached project's "case_1276004-Project.zip" Scene labeled "SampleScene"
2. Enter the Play Mode
3. Observe the Texture on "EditorVersion" GameObject
4. Observe the Texture on "LoadedVersion" GameObject

Expected result: Textures should look the same
Actual result: Texture loaded during Runtime is of lower quality

Reproducible with: 2018.4.28f1, 2019.4.13f1, 2020.1.9f1, 2020.2.0b7, 2021.1.0a1

  1. Resolution Note:

    Both the imported and the runtime texture are identical when using equal importing setup.

    The main difference was that "Alpha is transparency" is enabled on the version inside the texture importer.
    This causes some pixels (with alpha == 0 ) to be different due to alpha dilation.
    When disabling this option, I verified that the pixels of both textures are binary identical (on the GPU).

    Artifacts present in bug repro case seem to be the result of the specific rendering setup (rather than a bug).
