If a browser claims to be Headless Chrome, you believe it. Nobody has a reason to lie about that. The interesting question is the opposite case: is somebody claiming to be a normal Chrome, but is actually Headless Chrome (or an automated member of some other browser family, or not a browser at all but e.g. a Python script). So if you take a Headless Chrome instance but change the User-Agent to match that of a normal Chrome, does the detector think it's not headless?
