Difference between 1.1.1.1 and Warp?

When I entered 1.1.1.1 into Brave browser on my Samsung Galaxy A34 5G, it prompted me to install some app from CloudFlare. I did it and apparently I'm given access to a free VPN on top of custom DNS provider thingie from that company. Of course, they offer a premium VPN but I'm too cheap to pay for that shit. So will this really allow me to bypass blocking restrictions from private ISPs like those at Walmart and Home Depot or it's not actually a VPN? In my phone settings, it's clearly recognized and configured as a VPN by the app. Sadly I'm unable to use the Perplexity app while the Cloudflare VPN is enabled, and even switching to just their custom DNS doesn't work either.
