Unless your panel is calibrated this doesn't tell you anything useful.
factory settings other than brightness turned down to 10.
post 8 points out why with default settings , nothing to do with calibration and subjective as some monitors have adaptive contrast enabled on default so it's not showing the true range of the panel.
If calibration is out, it will affect when you see in that test irrespective of the panel type; It has everything to do with calibration.
