Any idea how to change the white *framework* background?

When Chrome first initialises, it presents a completely white "canvas" to the user before it has a chance to finish loading its GUI. Is there a way to change this to be dark mode compliant like black? Maybe in a flag setting?

To be clear, I am NOT talking about Chrome's dark mode themes, which work correctly once the GUI has loaded, and I am not talking about e.g. DarkReader which works correctly in applying dark mode to websites once they have loaded - I mean that split-second burst of all white when I first open Chrome at night and get blinded in my otherwise completely harmonious dark mode world. It's a nuanced distinction that makes it difficult to Google correctly, even within this subreddit.
