Most devices have a DPR greater than 1 and probably even greater than 2.
This means that the Cloudinary image they show uses half the available pixels on each dimensions.
In order to generate the photo for a DPR of 2.0, all you need to do is to set the
dpr transformation parameter to

Image resize -
Image resizing may cause some blurriness, especially when scaling the image up. If the original image is smaller then the desired dimensions a blurriness would occur. Regardless, this might be corrected with the unsharp mask. For example -
