The only 9.7'' display sold by E-Ink is the ED097TC2, which has a resolution of 1200 x 825,
while the standard 6'' display from E-Ink, ED060K[C|G]1, is 1072 x 1448.
The 6'' display has much more information - 157% as much - than the 9.7'' display - which on its side has 64% of the other one!
(1200×825)÷(1448×1072) = 64%
It's the smaller one the one with more content.
The 9.7'' one is 150DPI, the 6'' one is 300DPI: it means that for any square unit, the small one contains four times as information as the big one. But since the 9.7'' display is, of course, bigger (255% as big*), it compensates a bit and reaches two thirds of the information that the small one offers.
* (202.80 × 139.43)÷(90.60 × 122.40) = 255%
I corrected the point in the Wiki as:

Since people read text mostly on the device the ppi is not directly related to the amount of contents you can fit on a page. Typical computer screens are less than 100 ppi but people use small text all of the time on their computer screens without having problems. What you changed was a direct quote from Onyx so you should take it up with them. I have removed reference to comparison with 6" devices which come in a wide variety of ppi and 300 ppi is no where near the standard. It is the maximum currently available. Typically most folks will have no trouble reading 10 point text easily on either device although if they compare them side by side they will notice a difference is the quality of the text but 150 ppi and even much lower is still easily read.
