Regression
Yes
ACES Tonemapping causes banding artifacts and negative values in ColorGradingLUT when HDR is enabled and "High Dynamic Range" Grading mode is selected while Android Platform is used
Reproduction steps:
1. Open the attached “IN-98962.zip” project
2. Make sure the Android Platform is selected in the Build Platforms
3. Open the “SampleScene”
4. In the Scene view, observe the Sphere GameObject
Expected result: No banding artifact is visible on the Sphere
Actual result: Banding artifact is visible on the Sphere
Reproducible with: 2023.2.0a18, 6000.0.47f1, 6000.1.0f1, 6000.2.0a9
Not reproducible with: 2022.3.61f1, 2023.2.0a17
Reproducible on: Windows 10 (User reported), Windows 11
Not reproducible on: No other environment tested
Notes:
- Does not reproduce if the Windows Platform is selected, even if the Vulkan Graphics API is selected. With the Android Platform the issue reproduces with both Vulkan and OpenGLES3
- The issue only reproduces if on the “PC_URPAsset,” HDR is enabled under Quality settings, and the Grading mode is set to “High Dynamic Range” under Post-processing settings. Additionally, the “ACES” Tonemapping is set on the Global Volume GameObject
- Inspecting the ColorGradingLUT in RenderDoc shows negative values in the darker/banded areas of the LUT

Is this issue gonna be resolved? We have multiple projects and we can't update it past unity 2022. Nobody uses aces in their projects?
