Yes, here's an example using an RME device. On Gearslutz DA/AD thread, @Archimago shared his RME ADI-2 Pro FS loopback recording. The RMS error was reported as -44.3dBFS for left channel:
That's not that great for a high-quality device with objectively low noise and low distortion. Let's see what PK Metric reports for the same loopback file:

-81dBFSPK (new units ) Almost 2x lower, and below audibility.
Here are my results for the Antelope Audio Zen Tour on the gearslutz material. Originally reported as -56.9 db on the left channel which is 12.6 db better than the RME results. On the PK metric the table is turned with the RME scoring 9.1 db better.
