Display Color Export Issue

[Ziethriel]

Description
When exporting a USD file with vertex colors for displayColor, the exported colors are significantly darker then the values set in Maya.

Steps to Reproduce
Steps to reproduce the behavior:

1. Create new scene
2. Create mesh plane in a group
3. Assign vertex color HSV (360, 1, 0.5) RGB (0.5, 0, 0)
4. Name Color Set "displayColor"
5. Export ASCII USD file with Display Colors option checked
6. Open USD file in desired text editor
7. Notice the display color that was written is (0.21763764, 0, 0) instead of expected (0.5, 0, 0)

Expected Behavior
I expect exported displayColors in the exported file to match the value applied in Maya

Specs

• Windows 11
• Maya 2025.1
• Maya USD 0.28

Disregard, after closer evaluation this linear sRGB to sRGB is expected, Substance painter isn't applying the color transform back when baking vertex colors. I will open the issue with them.
