The difference between uncompressed size and physical size of a raster,

 

I couldn’t figure out what might the uncompressed size indicate for.

 

For example, the raster below has 1.5 GB as physical size while the uncompressed size is 1.1 GB. How this might be explained.

Other example, the physical size is 13 MB and the uncompressed size is 111.1 GB

What might be the explanation for these two cases?

 

 

Thank you

 

Best
