What are the key differences between the Audi A8's Matrix LED and the HD Matrix LED headlights?

I am considering purchasing an Audi A8 but am unsure of the difference between the Matrix LED and HD Matrix LED headlights. Can someone explain the technical aspects and which one is better for driving at night?

The Matrix LED headlights use a camera and sensors to adjust the light beam for optimal visibility and avoid blinding oncoming drivers. The HD Matrix LED headlights take this feature a step further by using additional cameras and sensors to create a more detailed and precise beam for enhanced visibility and safety on the road.
