Stair Finish - wood or paint
It could very well be a faux finish. More commonly found on older furniture, just stains grained on the wood. Can't tell for sure from the picture, but it looks like it might have been filled and then faux grained. This is why some areas appear to be mahogany while others don't. But this is pure speculation on my part.
Even though there may be more mahogany in the house, it's most likely doors or trim.
The stringers (in the picture) weren't usually done with mahogany.
My suggestion (and it's only on opinion), is to paint the risers, stringers and pickets and go natural with treads and hand rails.
