Upscaling isn't high res at all. To really have high res the original texture needs to be size 4096x4096. The low res texture then is a scaled down from the high res one. You don't scale up low res to get high res, that's not high res at all, still low res. A scaled up low res texture will still look bad in a high res image. If you would sell a scaled up low res texture as high res texture you would actually be deceiving your customers. Try rendering a really large render with this scaled up so called high res texture and you will see the flaw in this practise.
