It actually does look like that’s the case and it’s never enabled, it was left in the Chromium source as a TODO 7 years ago (with no action since and likely none coming):
“ Sadly the hack to get DX11 decoding to work on Windows 7 does not work. We can get a pointer to the MFCreateDXGIDeviceManager function and the device creation works. However the IMFTransform we use for color space conversion does not exist on Windows 7. There is a color converter DMO which technically could work. However it needs the video samples to expose functioning IMF2DBuffer interfaces which is not the case sadly.
I left the code to get the pointer to the MFCreateDXGIDeviceManager function under an ifdef for Windows 7. I will look into this at a later point in time. "

I see, this makes sense then. Thanks for the constructive and thorough feedback, much appreciated. :)
As for Nier Replicant, I tested the game in Windows 7 mode and it does try to load mshtmlmedia.dll. This, along with the comments from the Windows 7 users, should be reasonable evidence that it's needed.
