try DOILEAK that will catch you out the ip checkers arent thorough enough, bascially the doileak checks for DNS on your browser and gives you the option to check for torrents using either TCP/UDP. If youre not running a dns your isp provider can show especially in google chrome also chrome has a vulnerability in WEB RTC you need the extension as to block it otherwise your ip can leak through that too. Edge browser is better but still can show your location as when http requests are sent if they fail location services kick in and use other protocols to locate you. Turn off location services in edge. The last vulnerability in windows 10 is if you have IVP6 enabled that can show your ip address too
heres a link to in my opinion the best sites for checking your ip
