That's correct, SFSafariViewController does not afford app devs any usage information whatsoever, is run out-of-process, and uses separate cookie/localstorage/etc from both normal app webviews and Safari proper making tracking more difficult.
Also unlike Android's Chromium webview, SFSafariViewController utilizes the content blockers and extensions the user has installed unless the user specifically requests otherwise, so there's still some level of ad/tracker blocking happening.
