You seem to be interpreting my reply as a challenge to your comment rather than taking as support to it. The original comment made an incorrect statement-as-fact with b&w 1/0, yet TFA clearly stated it was grayscale. Your comment challenged implying TFA was not read, so I just backstopped your comment.
Your comment implied that your citation makes reading the article unnecessary, in the context of my initial comment. Since your citation didn’t mention the difficulties I was alluding to, your comment seemed to be missing my point, and to those who didn’t read the article would give the wrong impression that my comment was about grayscale.
