Why do my linear textures look different in the editor than in the mobile build?

I have linear textures for a skybox in my application and I use the Linear color space. In the editor, the skybox looks purple (which is what I want) but once I build on mobile (Samsung S8) for GearVR, the skybox is blue.
I tried unticking the "sRGB (Color Texture)" parameter in the texture settings and as a result, my skybox is paler in the editor but once I build it, it gives me the exact output I want (the original purple). If I switch to the Gamma color space, the skybox looks purple in the editor and build. There is something weird going on and I do not have much experience in colors and textures.
Can someone help me?
Thank you in advance!
