It is a completely different quality of light
- eINK without backlight is a full passiv display.
- eINK with backlight is not fully passiv for the paper.
- OLED or AMOLED in blackPDF mode ("night mode") is fully passiv for the paper and not fully passiv for the text.
- OLED or AMOLED in standard mode is not passiv for the paper and the text (passiv only for prixels of the text caracteres in full black)
- LED (laptop, ipad, not AMOLED tablet, etc.) in blackPDF or standard mode is not passiv for the paper and for the text

In black night PDF mode, OLED or AMOLED put on a led only locally on each pixel of the text. So it's really better for the eyes than a classic laptop or tablet with LED display and I can appreciate this difference when I read many PDFs.
And it's really speedy and fonctionnal modern device.
In the dark, I put the AMOLED screen flat to don't receive light of text directly in the eyes.
I use AMOLED with night mode everyday and my eyes are happy.
I recommand to try to read on an AMOLED device in night mode before to buy an expensive eINK 12 or 13 inch device
