But I had those tiny white dot on my iPhone 6 and got it exchanged. They call this dead pixel and isn't it the same for the Kobo (Small white dot that shows on a blank white screen)?

No, it's not the same; they're completely different screen tech. LCD screens are made of pixels. A bad one is generally a stuck sub-pixel (bright; a colour)/stuck pixel (bright white) or "dead" (black).
Frontlit e-ink screens are not made of pixels in the same way that LCD screens are; they are made of microcapsules. These can sometimes burst, leaving a fixed dark spot on the screen. Bright shining spots are never due to these; they are light guide defects/damage, or dirt.
