If something is not noticeable when it gets "better", but it leads people to notice other stuff is "worse" over time, then I'd argue it's not actually a good thing to get.
Imagine if someone said "this food won't really taste better to you when you first eat it, but after 6 months you'll find other food tastes worse". To me, this would not be a selling point.
