It's not just Libra, It's Clara 2E as well. Just a month or so ago I sent my Clara 2E for a warranty swap due to charging issues. I hope I won't find myself in a similar situation again and they'll send me a colour one as a replacement. No one who just reads normal books has anything to do with colour and I don't want to pay the price of having a second filter dimming the screen. Ugh!
The Canadian website has no listing for Clara, Libra 2E. But there's a "Kobo Clara BW", not sure if this is the same device with a new color and branding, I'll do more research.

Edit: It's not. According to "https://blog.the-ebook-reader.com/2024/04/16/kobo-clara-list-of-differences-between-4-models/" The notable difference between 2E and BW is the use of E Ink Carta 1300 screen instead of E Ink Carta 1200 screen, promising better contrast..
