That was due to compression, however, not upscaling. Related, but not similar :)

Upscaling could be described as the decompression stage of a lossy compression algorithm

A compression algorithm knows which data was lost and can optimize the discarded data for a good lost data/saved space ratio. Data "lost" by a low resolution sensor most definitely does not fit this description. Imagine saving a FullHD png instead of a 4k jpg - the former is most likely far worse.

It's not too dissimilar, I agree, but there are differences.
