While being more expensive even further decreases your niche size, it still isn't obvious to me that this should be enough to prevent the niche from existing. I am one of those customers you talk about who has a lot of obscure preferences (I can't call them requirements because literally not a single existing phone matches all of them and yet I still buy phones). A phone that met most of them would be something I'd be willing to pay a pretty good premium for.
