Thanks- I appreciate that!
Below my first section about ICC files I document a decent (temporary we hope) work around to getting accurate photo prints.
ICC Files: After doing some digging I found out on my own that in reality there is one (and only one) ICC profile that is included with the TS 9520 printer: CN_IJPrinter_Profile2015.icc
I derived this conclusion by looking at the .CAB file that Windows 10 stores as a backup after the printer is installed. The specific file name is: ts9500p6.inf_amd64_60e6da249cb7afd6.cab*
Windows keeps a number of its own generic ICC profiles, as well as any profiles that a manufacturer like Canon might use during driver installation in the following folder. (C:\Windows\System32\spool\drivers\x64\PCC\)
Within this CAB file we have 147 items; mostly DLL files, a couple of INF files... Basically variations dealing with different Windows environments, mostly for printing and I think also for scanning. And... exactly one ICC profile.
*Note .CAB files are like WinZip files and are commonly used for installation files. They are also used as compressed archive files within the Windows system. Most software companies use this format, though sometimes they are wrapped into/hidden in an .exe installation file.
My Work Around for Photoshop Users:
Note that I'm using a color calibrated BenQ PD2500 monitor with the Spyder X color system so my solution may not work as well for all setups, though I do think it'll work better than the deafult settings for just about everyone.
How I arrived at my conclusions: I set up a half page of gradients and known photos (both landscape and portrait) plus some basic RGB and CMYK colors squares so I could do some print testing and experiment with what settings we have control over. After some research plus about six test prints, here's what worked for me, giving a much more accurate screen to print match out of Photoshop.
Step 1: Photoshop Color Settings (Edit/Color Settings) are as below
Step 2: Photoshop Printer Setup:
Photoshop Manages Colors
Printer Profile: Canon IJ Color Printer Profile 2015
Rendering Intent: Relative Colorimetric + Black Point Compensation
Step 3: Printer Setup/ Print Settings...
Best Quality (to Pro Luster paper or whatever your paper is)
Leave the Quick Setup tab and go to the Main tab.
Select Manual for the Color Intensity section and then select Set...
Under Manual Color Adjustment/Matching select: None
The above should get almost anyone a lot closer to decent (accurate) photo printing out of Photoshop. However, even with all the above steps, I was still only about 75-80% color accurate, (printed images were significantly darker/more saturated than they should be).
Thus I set up a Hue/Saturation Adjustment Layer (which I'll save and use for the time being for any photo printing). The beauty of an adjustment layer is that you apply it only as your last step, and only for printing so it's not a permanent alteration to the image.
My settings:
Master/Saturation to -15
Reds/Lightness to -10
Blues/Saturation -10 and Blues/Lightness +10
Again I make no guarantee this will be the solution for anyone else. Even for me it feels like a lot of workaround, but at least I can get photos printed that look reasonably close to what I took! As I said, even now it's at best 90% accurate but that's acceptable.
Hope the above helps someone else! 
These are the profiles from the TR8500 which uses the same printhead and same inks. Theese are what is missing (and acknowledged as so) from the TS9520 driver, If only Canon would DO something about it.
You might want to try them as I said, same printhead and same ink. But no guarantees from me.
