Less color output + no diff when using super_diff

[blaineventurine]

First, thanks for your work on this gem! It was indispensable in a previous codebase, and I'd like to get it working with my current situation, but I'm having some trouble. RSpec produces less color output and no diff with super_diff:

Here's my normal RSpec output:

super_diff does show the full hash (no ... obscuring properties), but it doesn't print it cleanly, there is no color, and there isn't even the key shown.

Ruby: 3.0.1
RSpec: 3.12.2
rspec-rails: 5.1.2
Rails: 6.1.7.6

I've added the default config to the rails_helper, and I've tried manually forcing it to show color output, show the key, changing the colors, etc., and I did have it working on a different project that was on the same major versions of Ruby/Rails/RSpec, so I'm kind of at a loss as to why it's not working now. Any ideas? I've even tried basic comparisons, like expect(q).to eq(2).
