Regression

No

PNGs imported with RGBA Half format are incorrectly converted when using Gamma Color Space

Graphics - General

-

How to reproduce:
1. Open user-submitted project (732951_Blizzard_TextureDepth)
2. See Gradient8bit and Gradient16bit in the Project window

Expected result: the images match Gradient32bit image when Gamma Color Space is set
Actual result: the images do not match Gradient32bit image when Gamma Color Space is set

Reproducible with: 2017.4.33f1, 2018.4.12f1, 2019.2.12f1, 2019.3.0b10, 2020.1.0a12

Notes:
Setting the Color Space to 'Linear' the images appear correctly

    Resolution Note (fix version 2019.3):

    Solved the issue where LRD images (for example PNG 8 bit/channel and 16bit/channel) where incorrectly gamma decoded at texture import when selecting a HDR graphics format (float, half float, BC6) when using the gamma color space. No color transformation will now be applied in this case, so the (assumed) linear content will be sampled unmodified in the shader. The EXR file stores floats which are assumed HDR. In this case the current behavior is that the assumed linear (HDR) content gets gamma encoded at import. PNGs (LRD) will therefor look different than EXRs (HDR).
