What about going to a carpet shop to see if they have any 'samples' the bits to show you what the carpet is like.
Like mismatched crockery at the table you could make a patch work on the wooden treads and keep them in situ with carpet tacks............ that is if they still sell such things....... or a staple gun.
Painting is such a hazard.
On our carpeted stairs i always remove slippers and go barefoot
