Couldn't see any buggy behavior here. All 3 Lines are shown the same way. Note: NotoColorEmoji is embedded as TrueType in your example, wile it is embedded as Type 3 here. AppleColorEmoji isn't available in my system, because it is Linux.

Then the problem is limited to macOS build of LibreOffice?
Noto Color Emoji (2.051) is a COLRv1 font. Support for OTF COLRv1 font support is bug 151057 and macOS especially is known to have issues with the COLRv1/CPAL fonts. And for what it is worth on Windows 11 attachment 206785 [details] does not display the Noto Color Emoji --even though it is installed locally. But the font does not render glyphs across multiple apps except in chrome browser.
