Most video displays have non-square pixels. Standard definition video processing resolutions are 720 by 480 for NTSC and 720 by 576 for PAL though both are 4 by 3 aspect ratio. You can argue whether tv standards count as modern, but there are a lot out there.

There will be cases where zooming doesn't change device-pixel-ratio. Mobile browsers tend to have a "fast" zoom out which doesn't change the layout (mostly), and that might not change device-pixel-ratio. I think that's OK for your use cases as long as device-pixel-ratio reports the ratio as if the page is "zoomed in".
