Greyscale image compression and sRGB settings are rendering different results in the Texture Editor versus the Material Editor and in game.

Material Editor (Texture Sampler = Greyscale):
[Link Removed]

Texture Editor (sRGB = False, Compression=Greyscale)
[Link Removed]

Material Editor (Texture Sampler = Linear Greyscale):
[Link Removed]

Steps to Reproduce

1. Import Included GreyscaleTest.tga
2. Set Compression to TC_Grayscale
2. Create an Opaque Unlit Material
3. Plug the GreyscaleTest Texture into Emissive

RESULTS: Texture Editor and Material Editor Preview do not match

EXPECTED: Both Previews should match.
