I'm a bit puzzled by this. Kobo's specifications say:

Display
7" E Ink Kaleido™ 3 display with FastGLR and Dark Mode
1264x1680
300 PPI—black-and-white content
150 PPI—colour content

In the EU, that means they have to deliver a product which displays black-and-white content at 300 PPI. Section 18(1)(d) of the Consumer Rights Act 2022 says:

The goods delivered under a sales contract must shall--
(d) be of the quantity and possess the qualities and other features (including in relation to durability, functionality, compatibility and security) normal for goods of the same type that the consumer may reasonably expect given the nature of the goods and taking into account any public statement in relation to the goods made by, or on behalf of, the trader or any other person constituting a previous link in the chain of transactions relating to the sales contract, including the producer, particularly in advertising or on labelling. (emphasis added)

That's an Irish law, but it's based on EU directives and all EU countries will have similar provisions (as will the UK). It makes it quite clear that if a product is advertised as having 300 PPI, then the delivered product must have that functionality. It surely can't be that Kobo is acting in flagrant disregard of this law. There must be some sense in which the screen does in fact display black-and-white content at 300 PPI.
