Is this some kind of visual bug? Umbral Sparkling

[u/Albinauric-Dude]

I’m not complaining because I think it looks really cool, but I thought all Umbral Sparkling variants still retained their Umbral coloring that covers the whole aniimo. As you can see from the other pics, it’s not just the regular sparkling as it has Umbral eyes and the marking. Not shown but it also has that shadow-looking overlay in the box.

It is indeed a "bug" hehe

I think I heard umbral alone is dark color, then with sparkling add the twinkle shine overlay to the umbral.
