Some of the data seems straight-up wrong.

I know this computer has more RAM than reported and it's definitely not on a 4G network either.

The APIs it's relying on to show you that information do implement some anti-fingerprinting mechanisms - things like available memory will be put into rough buckets rather than returning the exact amount you have.

It got facebook pixel wrong. I see zero DNS requests to facebook.com on NextDNS

That panel reconstructs what a pixel would send from your own browser values, locally, and never makes the request. NextDNS seeing nothing is the tool working exactly as designed.

what?

They're saying that the site simulates what would be sent to Facebook without actually sending the request to Facebook.

(I'm not sure if that's true, but I hope so)
