My Kindle Oasis 2017 seems to have broken. I love that it's screen (Seems to be just plain old "Carta" with no numbers) does not need the backlight on to be readable in even pretty dim lighting.

I recently tried a Kobo and couldn't believe how grey the screen was and needed the backlight in all conditions other than daylight.

I would just like to see a comparison between all the screens (Carta 1200, Colorsoft, etc) to try and know how it compares to my old Oasis without having to purchase and return it.

Anyone know of a good comparison site like what I'm describing?
