Realistically, the kWh is used to determine cost of ownership by most people, not environmental impact.

230~ USD a year to run a 600 dollar product versus the initial cost of a 2300 dollar display with little to no electricity overhead -- and both have similar rates of failure with regard to non-display components.. AND that's disregarding 'Samsung Vs. Small-Company-From-Slovenia' being a factor in the purchase.

I understand eink is unique, but that characteristic has to be sold to people as a trait that is worth the difference..

That's a hard sell, if compared directly to one another.

(p.s. backlit displays are tacky, but my house is covered in them. I love it. I'm a tacky kind of person, though.)
