Use a CustomLog with a LogFormat that contains %{Accept-Encoding}i. That 
fields will tell you, whether your http client supports compressed 

In addition you can set

DeflateFilterNote Input uncompressed
DeflateFilterNote Output compressed
DeflateFilterNote Ratio ratio

and add something like "%{uncompressed}n/%{compressed}n (%{ratio}n%%)" 
to the LogFormat to track compression easily.
