How much do you pay attention to gamut warnings.
None. It's unnecessary, buggy and doesn't tell you much useful. It treats 1% and 100% OOG the same. It shows you OOG colors when none are in the image (the bug or rather inaccuracy). Soft proof and view how the rendering intent handles this per image and forget the overlay. Certainly for output. Somewhat useful for the display in LR to show you what colors are
OOG on your display.
