It would be easy to figure out...

Next time I change my oil I'll take off the line from the turbo sump pump and While there's no oil filter screwed on I'll put a blow gun on the fitting and shoot some air into it.
If air blows out of the outer oil holes of the filter mount while the filler cap is off then I know the oil from the turbo is being filtered.

If air blows out of the filler cap it is not being filtered.
Maybe somebody can beat me to it!
