Because the launchd.plist is not a preferences container. It's not meant to be

Yes, but that is only meant for informational purposes; programs should not be 
making decisions based on that output, and that output is not (and never will 
be) reflective of the complete contents of the launchd.plist.

If you need to modify your program's behavior, you should specify different 
arguments or a different environment in the plist. That is what those entries 
are for.
