My suggestion is not mutually exclusive to your initial effort.
And nowhere did I suggest dumbing things down. Not sure where you pulled that from, or why…
I fully agree that this can be presented in a way that shows the differences better, but it will require more explanations, the data will be even more unfamiliar.
I show this using tools that many of the more tech-oriented audiophiles are already familiar with. Most people who do measurements use REW, everyone has the tool and can experiment with own measurements and ways to visualize things.
I observe that many tend obsess about simple ways to look at the data, typically the frequency response, without considering what happens in the time domain. I see people measure their rooms, and then show a frequency response chart, implied that this is representative of the sound that is heard in this room, which it clearly is not. But viewing the data in different ways, can indeed reveal a lot about what is going on, and relates much better to what we actually hear.
Dumbing it down would be to present some sort of number, and then say this represents the sound of a speaker.
