There are a couple of indirect ways to know it:

If you set the parameter to true and you don't have cuda, you will get a warning.

You can add --udebug argument to show more logs and see if the gpu version of the feature is used.

Run without gpu option enabled, look at the processing time, then restart with the parameter enabled, then compre with new processing time. If identical, it is probably not running it.
