LED main beams poor

Hi all. I have just acquired a 2017 A6 allroad with standard LED headlights (not matrix). Although the dipped beams are fine the main beams seem very poor  and lacking in power and don't light up the road nearly as well as other cars I have. 2006 BMW z4 coupe with HID lights and 2008 Volvo XC70 with Halogen lights. both are much better.  Is this normal for Audi or do I have a fault ?  If this is how they all are then it is very disappointing and definitely not an improvement in technology. The auto dip is off but I didn't notice any difference when it was on. I have seen another post about the having wrong coding, but it seems a bit unlikely in this case as the car is one owner before me and completely unmolested as far as I can tell. Many thanks for any observations. 

Apologies - I posted this in the C6 forum yesterday, but couldn't see how to move it, hence the re-post.
