Were these screens e-ink, wouldn't they allow for doors that are better insulated? This could yield lower power consumption, couldn't it?

On the other hand, door insulation might be insignificant if the fridge is opened often enough. Which is likely what any retailer hopes for.

Given the importance of color to branding I think e-ink is a nonstarter in it's current mass-produced form.

Colour e-ink is available for retail purchase, and the colour reproduction is passable.

The refresh time is big fractions of a minute, but that's OK for static displays.

Obviously that misses the entire point of this parasiteware, which is advertising and tracking.

That's a good point, and tbh I was aware of color e-ink but I assumed the price difference was enough to be a non-starter for a (parasiteware) company.
