From what I can tell, the XTZ kit does not build EQ filters or provide a way to apply them. It just provides a way to measure your system's response before and after changes that you make yourself and compare to see if you're taking your system in the right direction. Those changes might include adjusting locations for the listening and speaker positions, moving other furniture, adding/adjusting room treatments, adjusting subwoofer settings (if applicable), or even setting the graphic equalizer or applying Audyssey® via your Marantz SR5010.
The tools it provides look pretty helpful, but Acourate from AudioVero combined with Roon from Roon Labs provides a more complete solution for actually building and applying room correction filters. Of course, it's best to get the room dialed-in as much as possible acoustically before messing with room correction. The XTZ kit could definitely be handy for that.
