The double price is not true either Kobo or Amazon. Sure if you compare Paperwhite ($120) to Oasis 2 ($250), but those 2 have a different target audiences. Is the Voyage ($200) worth it for $80 more than the PW at the same size? Depends on your needs. The 7" Oasis is an upgrade from the Voyage class rather than a PW class. The price difference shrinks to $50 from Voyage to O2.
As for Kobo, you don't have a 7" ereader. You go from Aura 2 6" ($120) to H2O2 6.8" ($180) to KA1 7.8" ($230). Here you somewhat pay for increased screen equally. But you also go up in specs going from 212ppi to 265ppi to 300ppi. You may not be able to tell the difference, but it is not simply a bigger screen size.
A 7" Paperwhite class ereader might be what you have to wait for. But right now there is no non-premium 7" ereader. Considering only screen real estate area a Kobo is a better value per $ compared to Amazon's offers.
