How dark will this get?

I'm almost done with book one, and loving every second of it; the characters, the prose, the worldbuilding! However... I watched a ton of videos saying how dark this book is (just this book, not the series as a whole) and I must say, it is really mild as of now, perhaps a little darker than ASOIAF, but not the nihilistic triggerwarning fest they warned me about. Does it get darker in later books?
