Developer Notes

Colour textures should always render with sRGB and linear should be used carefully in specific circumstances say as part of the shader maths (e.g. mask textures or something).

With sRGB = False:

Reproduced in 4.7 Preview 3 Binary

Reproduced in Main Promotable-CL-2408355

Steps to Reproduce

1. Import the attached ColorTest.tga Texture
2. Create a new Sprite from the Texture
3. Open both the Texture and the Sprite Editors for side by side comparison
4. Set sRGB = False.

RESULTS: See Attached Screenshot. Two Editors show different images

EXPECTED: Two Images are the same no matter the sRGB setting

NOTE: I have also tried to alter the DefaultSpriteMaterial to use a Linear Color Texture Sampler node with no differing results.
