What made the appearance of these images rather bizarre is the fact that they were located in the Galaxy Note 8 section of both websites. It is quite possible that the person who was responsible to maintain these websites has wrongly named the files for these images.
Here is a side-by-side comparison between that section inside the Galaxy Note 8 page for Samsung Russia and Samsung Malaysia:
But do note (heh) that there is currently no direct proof that this copper-coloured device is the Galaxy Note20 Ultra. Then again, none of the existing Galaxy Note models carry this particular camera module which sports similar design as per Galaxy S20 Ultra that was released earlier this year. Additionally, these pictures are quite close to the renders that were created by OnLeaks/Pigtou and Concept Creator/LetsGoDigital which were based on existing information that has been leaked into the Internet. The photo of phone cases that was posted by the famed serial leaker Ice Universe is also another evidence that the images from Samsung Russia and Samsung Ukraine’s website are likely Note20 Ultra. Both images have since been taken down from the websites but all in all, this is a massive blunder on Samsung’s part. Nevertheless, the company still have plenty of things to be revealed about the Galaxy Note20 series though, so expect to hear more from Samsung soon enough.
