One thing I learned is that screenshots aren’t always the best option if image quality matters. I had a similar situation when I was collecting pictures from a food festival and wanted to keep them for a personal folder. I started looking at tools that let you work directly with the Instagram post instead. I usually check the image after saving it to see whether the resolution is still good. I also find it easier when the process doesn’t involve lots of extra steps. For occasional downloads, I think keeping things simple and checking the final file is usually enough.
