I've just come back to look at this after your comment and it is now solidly blue and black to me!
I've turned the lights down in the room I'm in so that may have had an effect?
I'm the same, looking straight at it all I can see is white and gold. Like a bright gold even, it's not even brown.
If I look at it in my peripheral vision it's very clearly blue and black though 🤷.
