If you compare the images with the QR code in the app and on the Trezor Safe 5 device, the images will be different, but their decoded content will be the same. As far as I understand, the images should be identical, because this can cause some confusion.
Also, it would be useful to add a button to save the QR code image in PNG format. Sometimes taking screenshots is not very convenient when you need to transfer a QR code.
