TCL is the same, as are likely every brand of TV. They are not all the same --- even within the same manufacturer. A lot of newer firmwares will launch into setup every time you power up if access is not configured. The TV configuration data is most likely being saved/retrieved from their cloud. This serves as their connectivity test. Without wifi setup, my new Hisense 4k "budget" model does this *unless* you run it in "store" mode. Dealing with setup on every power up is possible --- but obviously highly annoying over time --- and this is by design. The manufacturers desperately want the data collection $. It's the only way some of them make money.
