https://chromium.googlesource.com/chromium/src/+/lkgr/docs/chromium_browser_vs_google_chrome.md https://chromium.googlesource.com/chromium/src/+/lkgr/docs/c... documents the differences on Linux (given it's the only platform which regularly has both packaged). That does seem to miss the EME CDM, though (I'd write a patch for it, but I'm a bit busy at the moment!).
