I am hoping someone can answer my query as it may well apply to B&W film images as well as those taken with digital camera.
Now cameras with B&W sensors are available and even those with colour sensors can be converted to B&W only, my question concerns how they and/or scanned B&W film images are handled by e.g. Lightroom or Capture One. Normally a RAW, TIFF or DNG image will be imported into the software and handled as a colour image. If one wants a B&W image from a colour image a second process will do that conversion. My question is what happens if the original image is B&W?
I use LR and have to confess that I have not seen a button to indicate the original image is B&W, so apologies if there is one. Does this mean that the software treats it as though it is colour, as it would if Bayer or Fuji-X with its colour pattern? Or does it treat each pixel as though it is just has a bit value from black to white?
My question is therefore how does one import a B&W image as that, not as a colour image would be?

Yes to your last sentence, ie LR knows it's a monochrome file.
You can test this yourself.
Open a colour file in PS (into ACR) then into PS (leave as colour).
In PS convert to B&W
Image -> Mode -> Grayscale
Save as a tiff, jpg then import into LRC and play
