I currently don't have access to Teleinfo, my Linky is still outdoor, so I can't tell but if you ask for your data to Enedis the CSV file you get only shows Energie active, either with daily or hourly reports.
For hourly reports, the column 'W' contains the mean value for the period and as the period is half an hour, you have to apply a 0,5 coeff. to obtain the energy in Wh.
That way it matches the daily report that shows the counters values in Wh.
Regarding hidden power consumption I was surprised with the DIN power monitor Eastron SDM120 Modbus that consumes about 0W but 15VAR.
