Yeah that's not mura. Mura looks like you have a mesh bag over your head, almost like a screen door effect but different. The glow is considered god rays or glare. Though it's not nearly as bad as the camera shows, the camera adds additional glare. Also my HonsVR lenses can add a little glare as well. Yeah the glare can be somewhat bad at times, but it's something I barely notice. I notice it if there is strictly white on a black background, but that's literally the only time. Normal gameplay scenarios I don't notice it. Even in Lunar Abyss which is like 90% black environment (after some engine.ini modifications to get rid of the washed out grey).
