Bad optics aside, it doesn't actually reflect reality. See my other comment. You can enable basically all the privacy settings and still pass turnstile. Tor browser in a VM passes it, of all things.
It tripped "Canvas Randomization Detected". See the last screenshot.
Cloudflare's demo page still treats that as a pass, but complains about it. As is often the case with Cloudflare, I expect that they'll then take no responsibility for sites that use more aggressive settings.
