I'm not sure what you mean by this. Upsampling does not make the
noise more intense at any fixed spatial frequency of the original

Who is talking in that context?

I suggested that when you upsample a low-MP image to meet the higher-MP one, its real image noise, relative to the higher one, is now apparent, and no longer "hiding" by having a small displayed image size.
