Maybe, but LCD panels are a light source, so it's not apples-to-apples. I _perceive_ eink as higher contrast than any LCD.

That is odd as I definitely do not perceive that.

My Kindle has much less contrast than my iPad, phone or computer - albeit I have brightness turned up.

I only use the Kindle as its battery will last over a day if reading my iPhone will not and also if reading in bright sunlight.

That depends on the external illumination. LCD contrast goes to shit under bright light.

It's bad but 1000+ nit displays under indirect light on sunny days seems competive with ratios around 4:1.
