Android ASTC HDR Artifact when switching to Android Platform

Vulkan

-

Steps to reproduce:
1. Open the attached user's project "ASTCHDR.zip"
2. Open the SampleScene
3. Go to Build Settings and set the target platform to Standalone
4. Notice the sun in the Cube object is rendered correctly
5. Switch the target platform to Android
6. Notice there is now an artifact visible in the sun (there is a tiny dot near the center)

Expected results: the Cubemap is rendered correctly
Actual Results: the ASTC seems to have suffered some kind of overflow during compression, causing an artifact. (See attached Artifact_Editor_ASTC_2021_Repro.png)

Reproducible on: 2020.3.45f1, 2021.3.19f1, 2022.2.0a14
Not reproducible on: 2022.2.0a15, 2022.2.9f1, 2023.1.0b5, 2023.2.0a5

Environment: Windows 10 22H2

Notes:
-The artifact is visible in the Editor when switching the build target to Android and also in Android player builds. On Android, I could reproduce the issue on a Moto G4 and a Samsung Galaxy S21.
-The issue is not reproducible in ETC2 nor in Standalone builds

  1. Resolution Note:

    Non critical issue, fix requires updating compression algorithm, which could cause unintended quality changes in projects after update.

  2. Resolution Note (2021.3.X):
