Rift Walker Prime Sigil still not matching other metallic texture colors

[Chaos.Blades]

The Rift Walker Prime Sigil metallics are still not taking color the same as all other metallics. As you can see from the below (if your monitor is not completely terrible) the sigil is a slightly different hue than the rest of the metallics despite using the same color as all the other metallics (Center Yellow in Shamrock). I made the sigil as large as possible to see this issue more clearly.
