OK

You can build spice-server with compression statistics. Uncomment line 94:

//#define COMPRESS_STAT

Then, run QEMU with the environment variable SPICE_DEBUG_LEVEL=4. When the 
Spice client disconnects, QEMU will show a table with statistics of all the 
compression algorithms used during the session. In my tests, LZ4 was used 99% 
of the time.

Thanks for your help
