What kind of sensitivity? Remarkable doesn’t use backlight, so it’s almost a paper like experience. The other brands that use backlight usually go from whit to yellow or orange like. But you can switch it off. I’m not used to backlight as my wife, but very few times I’d like to have it.

I use a paper white to read books, pretty much exclusively. Oddly, I find it best to have both the backlight and an external book light, so I guess that says something about my eyesight.

Thanks for the information
