From what I can see, the 1K version is shrinked to smaller width and, as a
result, there is an expected 
blurring due to pixel aliasing (partial overlaying). I can't make out what
the ORI picture shows, but it 
seems it's just a larger version of an aliased image section. There's
nothing wrong with your software, 
these are typical effects in image processing.
