Question about Leica Profiles under LR

Hello,

By default, RAW photos taken with a Leica Q3 are loaded into Lightroom with the Adobe Default profile. I have the possibility of choosing among several another profile called "embedded" under the "Legacy" category; which only appears for DNG photos of a Q3. Since LR is not supposed to be applied to a Leica profile (these being reserved for JPEG photos), what does this "Embedded" profile correspond to?

THANKS
