For some reason in my phone camera - "Open in browser" is not showing up if background is dark.

The original spec didn't allow for anything but "dark on light" codes. The official spec has been amended a bunch of times, but it's not always clear what version of the QR code spec an app uses. If it stuck with the original from 2000, it can't scan inverted codes. The spec itself has been amended in 2006, but the full spec is proprietary and needs to be bought, so not everyone may have updated their code if they have the old spec on a network share somewhere.

What phone and software? Old libraries looked for the contrast of black-on-white (not white-on-black), but I thought that was a solved problem now.

Black background, white foreground works fine on my iPhone 13 mini.
