It is not. It is incredibly successful, with many awards under its belt.

F76 did because again, it needed it because it was utter garbage on launch. There's a reason it had the nickname Fallout Seventyshit...
As for new RPG's other than Skyrim/Starfield that didn't get free long term support?
Mass Effect Dragon Age Assassin's Creed Monster Hunter Dragon's Dogma Horizon The Outer Worlds Persona Zelda BotW/TotK Octopath Traveller 1/2 Final Fantasy 15/16 Pokemon Sekiro Bloodborne Dark Souls 1-3 Immortals: Fenyx Rising Greedfall
Just off the top of my head...
Most of those aren't rpgs. And just because BG3 won many community awards doesn't mean its not a dumpster fire. Disjointed and bad story, bad mechanics, flat characters outside of romance to name a few things. And people expected Larian to fix those things like both they and their competitors did in the past.
