Understanding the image

As-salamu alaykum guys, I need some guidance regarding certain type of fuzziness or shadowing in the image, introduced after upscaling. I attached two images, first one is the image which has that issue of fuzziness or shadowing, introduced after upscaling and the second one which is the enhanced version of first one, don't have that much issue left. I able to fix it by using pixel cut background remover, i just simply remove the background and then add white color again and this helps resolve the issue to some extent or may be all. My concern here is that even after doing this technique when I saw the second image, I feel some shadows or fuzziness inside the logo or main box or wall type structure, now is this my own feeling and image is fine or image itself is still not completely fine. Just see it and comment what you guys think of it as I am a new contributor  and don't know much about such issues. Also now is it, valuable for the buyer to buy such an asset and ethical for me to sell such type of iamges. \
