Octospawn bleaching? Or something else?

[EpisodeMnH]

Is the Octospawn on the left in front bleaching? To give a little more background, when I first got this coral, it already had very light polyps mixed and splotched in, almost like a splatter type effect going on. But now seemingly overnight it’s like a perfect 50/50 light/dark split, right down the middle. Picture doesn’t show it best but it’s not actually clear, there’s still a baby blue tint to it and a neon yellow/green undertone to it. So it didn’t go ghost white like it traditionally would if it bleached. This almost seems like some type of split, although I’ve never seen a rapid color change like this after a split. What also makes bleaching iffy is the fact that a few weeks before this, I actually turned light intensity DOWN, not up. Was running at 50% for the longest, now it’s only 40%. So there was no recent light increase that would have potentially scorched it. All other Euphyllia in the tank are looking normal like they usually do, all pictured as well.

That's an unusual coloration.
