When scaling up a PNG, it is expected that the image will be blurry as it is a
raster image and not a vector image like SVG.

But I can see that reducing the image size can make it more blurry. Same in
Writer.

Original image I used to test:

Versions used:

Version: 7.5.5.2 (X86_64) / LibreOffice Community
Build ID: ca8fe7424262805f223b9a2334bc7181abbcbf5e
CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: threaded

Version: 24.2.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: 77fca616e0bd79e0b405fd0b3543cf8e94e15df3
CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: threaded

As I understand it, the blurriness when the size is reduced depends on the
combination of zoom level and screen resolution. Maybe this could be improved
by fixing bug 56468.
