Thanks so much for your recent update to the No Man's Sky page! Given as you seem to have access to the game, I'd like to suggest you also update the screenshots which are present since clearly they've changed since they were uploaded. See the editing guide for more info on that.
Also, speaking from experience, something which isn't listed in the editing guide is that it's generally better to update the images themselves, called "Upload a new version of this file" when directly viewing the wiki page for a given image, so as to prevent unnecessary duplication. If, however, the original image is a JPG, and you can provide a PNG of it - not a JPG converted to a PNG image, but a PNG image which is and always has been a PNG image - then you can upload the replacement image like a new image.
