Yes, newer/many Kobos have a good cast alloy backplate supporting the entire screen. I remember an iRiver Story Cover where the screen failed. The chassis had a cut-out for the Li-Poly cell and they almost all expand with age. The cell cracked the screen substrate. Probably plastic substrates are for cheapness and one might not have survived that; the plastic substrates & screens for truly flexible designs may even be a different design. I've seen photos & videos for maybe over 10 years and no actual retail products. I'd not be convinced on the long term life of a plastic substrate; certainly OLED plastic panels are shorter life than glass substrate OLED.
