Just want to share with you the results of room correction measurement between 7.1.1 to 7.1.3
The upper graphs are 7.1.1 and the lowers are 7.1.3

Taking the graphs at face value, 7.1.3 appears to have a generally flatter frequency response but perhaps adds a touch more bass. The really interesting thing is that the bass null at just over 50hz appears to be reduced. Considering that bass in that region is, if anything, increased, then the reduction is the null is remarkable. Quite how different firmware achieves this I'm not sure.

Is that a 'brick wall' at 20kHz on 7.1.3?

Did you take an average over multiple measurements or just one?

you will never get identical measurements. You only need to change something in the room, e.g. reorganize some stuff in a rack or moving a chair. And you will never be able to position the microphone exactly on the same 9 positions for Dirac.
