Yes, e-ink pricetags are one niche of e-ink devices. The other niche is e-readers (which are a luxury version of installing an e-reading app on your phone). Maybe the niche of solar-powered billboards (e.g. bus-stop signs) will also take off, but that's about it. E-ink is great, but it is niche and basically everything that you can do with an EPD, you can do with an LCD. E-ink screens are in the at best tens of millions, whereas LCDs are in the billions per quarter - there are over 6 billion smartphone owners in the world already, and LCDs are in everything from supermarket self-checkout kiosks to laptops to smart fridges, they utterly demolish E-Ink in scale. I love e-ink screens, but there's no denying the tech's business-case is rather marginal and that won't change anytime soon.
