LCD does provide a true contrast ratio of White to Black, so Yes the letters are sharper and more crisp on an LCD than they are on an eink. Heck even a physical book that is printed on a white page is much sharper than eink.
Now I'm not going to get into the whole lcd vs eink debate. It's what works best for the individual, Neither you nor I can tell anyone which is the best. I for one , happen to like both.
And who reads with the lights off? I do as do other nook color or iPad or Xoom etc owners can and do.
Each tech has their own advantages and disadvantages.
But what is growing tiresome, is saying a device cant be an ereader unless it's eink. Pure and total nonsense and opinionated garbage.

eink, does not emit light, is the most natural way to read. Nothing is coming from the screen so what you see and read is thanks to the natural reflection of the ambient light against the screen. A few of the benefits:
No parallax
On eink black and white particles move and reside on same layer, so when reading, everything looks and really is on the top of the screen, giving a true reading or paper feeling.
On LCD, the white color is coming from back light while black is coming from the front, the liquid crystal layer in the middle; that creates a shadow which gets worse if you read at angle, decreasing the quality of the reading experience and the legibility of the letters and whole content.
Less Glare
Self explanatory. Because eink screens are treated to be matte like a printed page, there is low or no reflection, so what you see is what you are reading, not the content plus additional light reflection, very common on all LCD screens (more or less noticeable in certain devices, depending of the overall quality of the screen)
No aperture ratio loss
The pixels on LCD screens do not have a full aperture ratio. E Ink screens have a 100% aperture ratio.
So when two black pixels are close on a eink screen, they join to create a true solid black (or white, depending) improving the image quality.
