Texture2D conversion appears to brighten colors

[SSM0770]

I have recently been exporting Texture2D for use in Blender (the texture is used for patterning between two colors) and had noticed some of the textures appeared to be extremely off. Upon further inspection it seems the texture exported by AssetStudio is brighter than the original Texture2D (The original Texture2D as it displays in AssetStudio on the right, exported PNG on the left. Changing the format it converts to does not appear to make any difference) Note that the blacks towards the bottom of the Texture2D are darker than the PNG, its minor to those not doing close examination but it makes massive differences in the appearance of the model I am applying the texture to.
