If the blob is an image, it's probably a base64 endcoded image, which means you can display it in your html by adding data:image/png;base64 in front of the string in a popup or somewhere else. Change image type based on what it is.

So as an infotemplate, you might write it as<img src="https://us.v-cdn.net/6038851/uploads/attachments/image_comment-458047-1.gif" />
