Do you have a report on this subject: experimental or simulated evidence?

Do you mean using the "data piping" option of DVB standards?

You can start from...
http://www.iana.org/assignments/multicast-addresses
...and...
http://www.iana.org/assignments/ipv6-multicast-addresses
...where you will find an up-to-date list of official assignments.

It is impossible to say how many addresses will be used in future and the use of "link local" and domain administered ranges means that it is non-trivial to get data on the number of addresses used (inc. overlapping/colliding address usage).
