Gumut warning with video limiter effect

Gamut warning with colors. I assume there are 3 reasons when the warning is shown. 1. Whites to high, 2. Blacks to low. 3. Color not legal for color space. Over saturated or not legal in color space. When it comes to hue vs hue adjustment in curves the warning disappears just by clicking on the color. 

I have generated this ai response. Which explanation is correct?.

If the gamut warning disappears after selecting a color using the Hue to Hue adjustment without making any visible changes, it may not necessarily be a bug, but rather a feature of how Premiere Pro handles color adjustments.
Possible Explanations

Color Space Re-evaluation: When you select a color with the Hue to Hue tool, Premiere Pro may automatically re-evaluate the color's position within the color space, effectively recalibrating it to fit within the gamut. This could lead to the warning disappearing even if no visible adjustment was made.

Threshold Adjustment: The software might have a threshold for what it considers out of gamut. By selecting the color, it may be adjusting the internal parameters that determine whether a color is flagged as out of gamut.

Temporary Glitch: While less likely, it could be a temporary glitch in the software. If the warning consistently disappears without any adjustments, it might be worth restarting the application or checking for updates.
