I generally defer to the DM's concept, as I've mentioned. But DMs who spend lots of time on really detailed settings are always a bit of a red flag to me.To certain extent true, but I personally would respect the GM's creation in the same way I would respect an existing IP (or more in fact, as it was something my friend had put thought and time into,) and the fact that I already do not know everything about this world would be a feature rather than a bug to me, as then I would have the joy of genuine exploration.
I like the act of creation in detailed world-building. I like reading about detailed world-building. But unless it's being used to inform the act of play rather than constrain it, I'm not a huge fan of detailed world-building mixing with roleplaying.
