Here are the LCR measurements with my UMIK-2 in the main listening position. My Macbook connected to the Denon 6700 via HDMI 2. The midi was set to 8-channel, 16-bit, 48 kHz (this was a mistake, I meant to use 24-bit, but it was left this way when I was troubleshooting the connection). The UMIK also uses 48 kHz sample rate. REW was setup to use the Denon-AVR sound device and I verified the 8-channel mappings for LCR, LFE, SL, SR were correct.
The spectrograms seem to have decent control under 200 msec, except maybe in the 100-300 Hz range. But there is not much of a red band -- i don't know if that's good or bad (I suspect bad).
The RT60s show a couple spikes in the 100 - 300 hz range for the LR, and a big dip for the center around 180 Hz.
The SPL shows a pretty big drop for the center around 180 Hz, which seems to correspond to a "peak energy time" spike in the spectrogram and a big dip the in th RT60. The left has a big dip around 360 Hz.
I'm not sure why the LFE shows about +6 dB over what I would think of as "smooth" -- I'll need to review the Audyssey app PEQ settings.
I could not figure out how to get the RT60 chart to display the time to distance conversion on my mac.

And this is the combined (1/12 smoothed) SPL. The LFE is a Sigberg Inkognito 10 on Preset #1. It is against the front wall on floor stands. There is a second sub (an older klipsch) on the side wall, on the Denon sub 2 output, but it did not seem to be used in the LFE test.
