Logic 7 HiFi and trunk floor bitumen soundproof mat

[Panta Rhei]

Hello, is this OE solution for Logic 7 HiFi Professional option on a Z4M?
This is how a floor looks under cover in trunk.

I got rid of that thing. I like OE solutions.
I though maybe it was somekind of BMW thing since it has got highest audio option.
