Wrong values in retina vs other displays

What is the current behavior?
Retina displays will always have values double that of regular displays. I am only interested in desktop, as I anticipate mobile is much more difficult.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. Your bug will get fixed much faster if we can run your code and it doesn't have extra dependencies other than zoom-level. Paste the link to your JSFiddle or CodeSandbox example below:
I am looking at https://codesandbox.io/s/zoomlevel-live-example-841ns / https://841ns.csb.app/, as well as testing in the console.

What is the expected behavior?
Ideally a retina display can be identified and its value halved so that retina and non-retina displays give the same value.

Which versions of zoom-level, and which browser / OS / node version are affected by this issue? Did this work in previous versions of zoom-level?
zoom-level: Latest
Browser: Chrome 81.0.4044.122 / FF 75.0
OS: MBP 16 on 10.15.

What numbers do you receive?
Zoom level is not an absolute value thus it does not depend on resolution itself.

On my Retina display I got 2x the correct value. I found this snippet, which does not suffer from this problem, but has its own issues. Namely, that it is based on width and so devtools and such can break it.

@bogus-e since i dont have any retina devices - could you please visit this sandbox and check the console of preview https://codesandbox.io/s/zoom-level-live-example-forked-5tygj1?file=/src/index.js
zoom in and out
there will be logs with several values - post them here please
