That's a strange thing to query: it is only defined if the image was a TIFF (Pillow's TIFF plugin), and it does not even discern binarized vs others: binarized would be .mode == '1'. This signifies BlackIsZero, which could be true for
- binarized
- grayscale 8-bit
- grayscale 8-bit plus alpha 8-bit
- grayscale 16-bit int
- grayscale 32-bit int
- grayscale 32-bit float
I don't understand the purpose yet: what did go wrong before?

That's not going to work well: binarization is usually more than a simple conversion – you have to find the best threshold, ideally localized across the image.

I dont know exactly if this is what you are expecting, but I tested it with RGB Images and was able to process those, even with postprocessing.
