BG3 can and bloody should shift industry expectations. Not CRPG expectations; industry expectations. And it is, as you pointed out, exactly about the economics rather than the game directly.
Larian, in terms of funding, company, and development team size, is comfortably on the low-ish end of triple-A developers. The only studios comparable to Larian in scale, are studios which basically only service a single, extremely well-established IP with a regular development and release cycle, using pre-existing engines and development kits. That is to say, low-risk, high-reward, cash dairies for major publishers.
