Segment descriptions

Hello

I am attempting to build a view of audience information within the AEP datalake.  I can see within the table qsaccel.profile_agg.adwh_dim_segments there is a column named description, but it does not appear to be populated with the description of the segment created in the Adobe RTCDP UI.  

What is interesting is the segment description of external segments is present, but not audience created in the rule builder and or via audience compositions.

I realized I can obtain the segment description via platform.adobe.io, but ideally would like to pull this information from the datalake if possible. 

Is there another object in the datalake which stores metadata about segments?
