Have you guys noticed that, in some third-party apps, the thumbnails or compressed images are brighter than the original images? A typical example is that the background color is displayed as white as the background of UITableViewCell in some screenshots posted online of UITableView. You will find that this happens on Twitter as well. At first, I thought that it's the problem of display. And I was confused because after I checked these screenshots from web on a PC, I found that those images were abnormal, too. So, I guess it's the problem of the compression of these images. And it becomes weirder. Do these apps share the same method to generate thumbnails and compressed images, and this method cannot work normally with iOS 14 Beta? Or something else?
