Should be noted that it's also behind a feature flag in Firefox (only in nightly!) and while basic support is there(no color profile support), further development doesn't appear to be happening and it's low priority: https://bugzilla.mozilla.org/show_bug.cgi?id=1539075 https://bugzilla.mozilla.org/show_bug.cgi?id=1539075 EDIT: Why the downvotes? This is the status on Mozilla's end for at least a year. If none of the browser developers care to push support, then the format is effectively dead.
