This is a personal preference thing. To you (and many others), the setting felt lacking in terms of specific detail, whereas to a lot of the setting’s fans it’s a key selling point. Personally, I prefer that From Software approach to lore, where everything is implied rather than directly stated, and there’s lots of room for speculation. It’s definitely not for everyone though.
My preferences are for about a further 20% detail

So yeah I think a good campaign in a POL mind set is great - but I think Mearls takes pushes it away from what I prefer form POL setting.
