Verizon has done a pretty good job with it so far in my experience. When it's been announced there are updates on the way, I've got them within a week. Pretty good timing.
Used to it would take sometimes 3 week to almost the equivalent of a full month to get it, but VZW has stepped it up and so has Samsung. I got a couple new wallpapers with mine( likely won't use em but good to have em there) and it really does seem like my camera-- particularly night mode has seen a performance increase, even though it wasn't specifically mentioned in the details.
