Well, I accidentally posted in the kobo forum initially (
https://www.mobileread.com/forums/sh...81#post4332381). The advice I got there led me to try a Kobo Clara 2. It seems markedly dimmer than the Aura 2 and I think it will work for my purposes, so thank you. I'm attaching a picture:

Unfortunately, the firmware the Clara runs has a worse Dark Mode than the Aura 2's Invert Screen! Where the Aura 2 actually applied Dark Mode to everything, the Clara 2 leaves the menus and the main screen white. (

Is there a way to get the old dark mode back? This thread (
https://www.mobileread.com/forums/sh...d.php?t=341175) mentions the change came out with firmware update 4.28.18220; can I downgrade the Clara 2 firmware to a version lower than 4.28 to get the old invert screen behavior back (it currently has 4.35.20400)
