I have Windows 7 iso 64 bit that I'm trying to install on my new 27'' Imac and then do the free upgrade to WIndows 10 once installed.

Bootcamp Assistant tells me "Boot Camp only supports 64-bit Windows 8 or later installation on this platform. Please use an ISO file for 64-bit Windows 8 or later installation."

But searching around it seems like it is possible, Apple lays out the instructions here but they don't follow:

https://support.apple.com/en-us/HT205016

What am I missing?
 
Windows 7 on Boot Camp is no longer supported on any new Mac. The article you linked is for older machines. If you look down at the bottom of that page, you'll see the supported Machines for Windows 7. Mid 2015 iMacs were the last version of the hardware that can run it.
 
It's listed:

iMac (Retina 5k,
27-inch, Mid 2015)

and the download link for the older bootcamp files are there.

Can I install it without bootcamp and then use the older support files, upgrade, then upgrade the bootcamp support?
 
Edited my post to reflect the mid-2015. Didn't scroll far enough down. Like it says, that's for Mid-2015, not the Late-2015 which you have. I don't know if there are any hacky ways to get it installed, so if someone else is familiar I am sure they will chime in. From a pure bootcamp method, it cannot be done.

Has anyone figured out how to install windows 7? I would like to run Windows 10 on my late 2015 I mac but I need to install windows 7 first.

Why do you need to install Windows 10 first? You can create installation media for Windows 10 directly from Microsoft and activate using your Windows 7 key. They changed that recently.

Does it work for oem versions of windows 7?

I don't think there are old support files for iMac 2015 late, the policy change is prior than the iMac 2015 late was introduced. You may face no drivers for Windows 7.

Try to install "VMware fusion" or "Parallel" in the OSX partition and create a virtual machine with windows 7 and upgrade it to windows 10. You should now have linked the serial to windows 10 so u can now install it to a new partition with a clean install with the installer you find on microsoft site.
