OpenGL ES 3.0上的sRGB Framebuffer

I am working on a OpenGL ES 3.0 Android project using Java. I need to implement gamma correction and somewhere I've read that sRGB textures would be supported in OpenGL ES 3.0. So my intention was to call glEnable(GL_FRAMEBUFFER_SRGB) before rendering into the default framebuffer.I am working on a OpenGL ES 3.0 Android project
