It is a fact that they do, and not by just a little bit. LCD display contrast is orders of magnitude better than E Ink displays (and OLED displays have, essentially, infinite contrast so even better contrast).
Higher contrast displays remain readable at lower levels of lighting than lower contrast ones can. The concept is much like dynamic range in music. That applies whether the display is front lit paper, a front lit reflective display such as E Ink, a back lit display such as LCD, or an emissive display such as AMOLED. The difference is very noticeable when one compares low contrast displays such as paper and E Ink to a much higher contrast display such as LCD or AMOLED. It also explains why LCD and OLED displays are much better at displaying grayscale images than E Ink displays, their much wider "dynamic range" means that the whites can be whiter and the blacks blacker, and hence a wider range of "greys" and differentiation between them.
There is no universally adopted way of measuring contrast allowing exact comparisons but, typically, paper has a contrast ratio of around 10, E Ink is a little higher than paper, LCD displays are typically of order in excess of 1000, and (as I mentioned) OLEDs are essentially infinity.
