Background blur (or background filters in general) are not a web-exposed feature, so it seems odd that Internals has a switch for some non-web-exposed feature that is only implemented by one port. It feels like this was something added for a UI feature in Chromium, in which case Internals isn't an appropriate way to toggle it.
