VSM Cached Page is displayed in grayscale in UE5.5

VSM Cached Page Visualization in UE5.5

Hello,
I wanted to visualize the VSM Cached Page for debugging lighting,
but I expected it to show green or red colors, and it only appears in grayscale…
Is this a bug?

I took a screenshot of the scene in the CassiniSample.
Thank you.

Move around, or have something moving in the scene, it will show colors. I was moving around in my scene (553) and the colors only last a fraction of a second before they are cached (grey):
