I switched over my router the other day and while I was debugging some minor issues I briefly had internet without Pi-Hole.

I was stunned by the prominence and intrusiveness by the ads on my Roku, even with already knowing it calls home several times a minute.

Once everything was back up and running things were back to normal. My setup is a dumb Spectre with a great screen with a Roku connected for Netflix and Plex/Jellyfin. Combined with a pi-hole it makes for a pretty clean experience.
