Good luck getting a relevant and specific response.

Unfortunately, the cover photos aren't very useful to compare contrast (that is the title of thread). They are different. The obvious thing is in the title block. The text is different which means that overall cover image has been handled differently. And if you look at the actual picture, the framing of the picture used in the cover is different. The one used on the Kobo is wider than on the Kindle. The easiest spot to see that is if you look at the birds on near the edge on the right. They are closer to the edge on the Kindle than on the Kobo. You can see the same thing on the left with how close the building is to the edge. So, are the differences that are apparent, because the screen is better on one than the other? Or were they already in the image when it was put into these books. That makes it hard to know if the differences we are seeing in those photos are differences in the devices or the original cover images embedded in the books.
And that, to me, is noticeable in @shaly's snippets. The snippet from the Kindle is clearly more detailed than the one from the Kobo. But, in @moorekom's photos, if you look at the back of the person in the photo with the Kobo on the left, that looks more detailed than the Kindle in the same photo. Maybe the image was processed at some point to emphasise the person and blur the background.
I went looking for the book in the Kobo store to look at the preview. The Australian store has a completely different cover (more like a logo with the title above and the author below). Trying the Kobo US gives a cover similar to that in the Kindle in @moorekom's photos but has a "Netflix" "sticker" on it. All that makes it hard to get an image I can look at and see how it looks to me on my devices.
The other problem here is that these comparisons are not just comparing the screens. Remember, the thread title says "better contrast" and the first post asks for "better screen". They are also comparing the source document and the other processing done of that document by the device. For text only, the comparison is probably mainly the screen. The exact font will have an affect, but, a little bit of open-mindedness can see beyond that. And comparing how multiple fonts are handled will give a trend for what is going on. For me, there isn't enough difference to worry about between the Kobo's and Kindles that I am seeing in the photos. It definitely isn't something I would notice about unless the devices were next to each other.
But, for images, there is also whatever is rendering the images. That blurs whether the it is the screen or something else. How the devices convert to grey scale is likely to have as much effect on the apparent contrast as the actual screen. As does whatever scaling has to be done to fit the image on the screen. And if you need to use the same image for the comparison. Otherwise, we don't know where the differences have crept in.
And for the record, in a lot of ways, I don't care about this. The quality of the screens and what is shown is well beyond any trigger point I have for problems. I still have a Kobo Touch and that does make me cringe. Especially when I think how good I thought it was when I first got it. Compared to the current devices, it is terrible. I look at these threads more from the academic view of seeing what people think, and whether I can see the differences being discussed. And to see whether someone has come up with a good way of testing. If I want to look at pictures, I am going to do it on my laptop or on my iPad.
And I have no idea if you will consider that relevant, or specific.
