--

-

How to reproduce:
1. Open the attached project “GammaRepro.zip“
2. Open “SampleScene“ Scene
3. Observe the color of the “WhiteImage“ GameObject (child of “Canvas“ GameObject) in the Game View

Expected result: The RGB color of the image is 255, 255, 255
Actual result: The RGB color of the image is 254, 254, 254

Reproducible with: 2022.3.2f1, 2023.1.0f1, 2023.2.0a18
Can’t test with: 2021.3.27f1 (“Vertex Color Always in Gamma Color Space“ option not implemented)

Reproduced on: macOS 13.4 (Intel), Windows 11 (by reporter)

Notes:
- Digital Colour Meter was used to test this on macOS
- Issue is reproducible in Player

  1. Resolution Note:

    This is probably a side effect of the tone-mapping that's applied by the HDS feature. Turning HDR off solves the issue.

    After investigation, we have deemed this a low priority issue that won't be fixed in the near future either because it is too costly to implement or because there are risks of introducing other problems doing so.

    If you feel this is a wrong assessment, please reach out again, providing more details about the impact of that issue.
