TechCrunch has a nice break down of the possibilities around this[0]
I am not sure how the color e-ink performs in this particular scenario with the monitor advertised compared to something like P3 enabled displays, but the tech has advanced that Gallery 3 panels[1] can produce 50K CMYK scaled colors are 300 DPI which is great for color accuracy, esp. in regards to physical materials (brochures, T-Shirts etc).
That said, they're likely using Kaledio displays here, Good Reads has a nice breakdown of them[2]
