Why the logos are not clear? See below:
It depends on what we can find on the site. If they don't have a higher resolution image, we will use with whatever they have available. If a site wants to provide such an image to us, they can make that request.
Also, your monitor scaling settings could be a factor; at the moment, we prioritize sharp text and our GUI library keeps applying the same text aliasing effects to our images that sometimes make it blurrier. We're trying to find a way to separate them apart, so only texts are aliased while the images are left alone.
Thank you @MikeT. Agreed this must be because of inferior quality of logo shared by the site itself.
You're welcome. We do have some ideas how we can look in other sources to grab a better resolution image and hopefully, we'll expand our Rich Icon service in the future.
