It may to you, but there is a mode to render B&W at 150 dpi because it can't support real 300 dpi. Certain white 1 pixel lines at 300 dpi mode will not render in white. Some ereaders call it "rainbow suppression".

So in reality true monochrome content can't be 300 dpi without artefacts. It may seem as sharp to some people, but the 2 x 2 patter of printed translucent dots that seriously reduce ambient brightness and contrast are always there. It's a physical fact the the sharpness is reduced.
Just like LCD or OLED at 96 dpi and the sub pixel addressing to make text sharper isn't anything like as good as a 192 dpi colour panel with no sub-addressing.

You need a 600 dpi eink panel for colour to be as sharp as 300 dpi and have no artefacts, but the contrast and ambient brightness is still rubbish.
