Beautiful floor! I don't think I've ever seen maple in that color. Are the stair noses are prefinished to match? You'd just use the floor boards on the stair, and the nosing to finish? That sounds pretty straight forward to me and you wouldn't have to worry about either the stain or wear layer; so long as the nosing is wide enough that you can attach it to the horizontal of the stair, not hang it off the front of the vertical surface [which can be done, but is more difficult]. Staining to match is also doable, especially if you are matching a wood with a lot of natural variation. With stair treads, you have a lot of unseen wood on the backs to practice on. A good paint center can help, but since the finish is semi-transparent the underlying wood plays a big role and they can't do it as accurately as they can match a paint. I've intermixed different colors from the same stain families for years. You just need to keep accurate records of what each mix is, and use a little common sense-- don't mix a 'regular' stain with one that has poly added, and read the label to make sure there are no restictions-- Minwax Red Mahogany will only accept certain top coats, for instance, so its a poor choice as part of your mix. But using the factory finish stuff will save you all that hassle.

I’m hoping that it’s not going to be too difficult to find the skill and expertise needed to prepare the treads. We’re in the greater Indianapolis area. Is this a unique enough project (preparing stair treads by matching stain and replicating hand scraped texture) that we might struggle to find someone? Quick Google searches suggest to me that many species of wood treads can be purchased online, including treads with various degrees of distressing, but I’d prefer to work more locally so we can see what we’re getting. I’m pretty sure the flooring store, which has a very good reputation locally, will be qualified to do the installation. I need to get back in touch with my contact at the flooring store for thoughts. I might also reach out the man who custom built our kitchen cabinets to see if this is the type of carpentry work he might do (he did a beautiful job on our cabinets).

A picture of your current color would help. Anything other than your run of the mill Oak stair treads are probably going to be costly. Try this company to see if they have any suggestions: https://www.advantagelumber.com/ipedecking.htm

@hallettco, it's been a long day.....totally forgot the OP said LVP in her first post between my first comment and second comment. I was looking at what appeared to be solid wood in the pic she posted. FWIW, my builder installed red oak treads after we had very light white oak flooring installed and he clear coated them. It's not off terribly but it's been a bone of contention between us. It's not horrible but he gave us a discount so I'm living with them for now :/
