Help identifying wallpaper please

[KateD]

Hi all, I’ve recently moved into a house which has lovely wallpaper in the bedroom, however there are a few places that need replacing as they are marked / damaged.
There are two colours, one is black, the other is cream / silver, and both designs are the same - which is two tone.
I’ve tried Cole & Sons and Sanderson, as there were other rolls of wallpaper left in the loft by both suppliers, but they’ve said it’s not theirs.
The pattern is very subtle - little dabs / shapes when you look at it face on, and then when you look at it from an angle it’s got squares made up of tiny dots (see pictures)
I’d love to replace the pieces that are damaged, rather than redecorating the whole room but am struggling to find who even makes this?
Any ideas please? Thank you.

Looks like a Graham & Brown paper, maybe domino spot
