why though? The graphics represented in the screen are already squashed and scaled, so you wouldn't be preserving their quality in any case. If you're worried about text, JPEG should still be able to handle it under high quality settings

We can ask the same the other way around: why do you want to use jpg if it results in a bigger size and worse quality than png?

But that's patently untrue: take this 10 MB example TIFF file as an example.

PNG Compression, max compress (=quality 9):

convert file_example_TIFF_10MB.tiff -quality 9 test.png

JPG Encoding, 99% quality (=quality 99):

convert file_example_TIFF_10MB.tiff -quality 99 test.jpg

Final file size comparison:

9.7M Sep  5 13:21 file_example_TIFF_10MB.tiff
1.7M Sep  5 13:22 test.jpg
2.5M Sep  5 13:22 test.png

PNG is significantly larger, and difference in quality between them is negligible

Dude. Did you even read what I wrote? PNG is bad for photos. Your example is a photo. Go ahead and try the same with a screenshot with text and menus showing.
