You’re probably right, but that doesn’t seem like much of an indicator for anything regarding the quality of the final product. Production was handled by Trigger and we don’t know if Netflix had any kind of supervision. Dungeon Meshi aired on all the usual TV channels in Japan as well, so Netflix isn’t the only licensee.
I stopped reading the manga after the erectile dysfunction at magic high school arc dragged on for months and ended with a relationship that still puts me off when I think about it. It’s like the author just can’t stop reminding the reader of what an unlikeable turd the MC can be. It is a very good story aside from those aspects, but that’s not enough for me to agree with your bold statement. I much prefer Iruma-kun, Overlord, Konosuba or Tsukimichi.
