Any way to use diffview .html to display comparison of local folders?

The diffview in TeamCity is really helpful, and I'm looking for a way to hopefully use it for a diff of my own (if that's possible)

I have a build config that that performs a comparison of an auto generated folder, against an expected folder. With the idea that if any differences are located, I plan to fail the build and display the diff.

Currently, I'm performing the compare with a simple python function using difflib, so currently I'm correctly failing the build, but simply outputting the diff hunks.
Is there any way I can use this data to generate a handy diff view using the html file?

Either that, or another way of diffing two folders using something built into TeamCity perhaps?

Here's my current output.
