To my understanding, Taylor has only one saddle spacing size - 2-3/16" as you measured. I vaguely recall people asking about other spacing before in Wood & Steel for BTO a long time ago, and the answer was a definite "no". I believe it would require re-programming the CNC machines that cut bridges and drill bridge pin holes, which is a big undertaking.
You are right that the dimension differences will be tiny. I've never felt any difference finger picking on 1-11/16" or 1-3/4" necks, or even the few 1-7/8" necks I've tried. Admittedly, I don't appear to be all that sensitive to that dimension, like I am to nut width. I learned to finger pick on a D-28, which has 2-1/4" bridge spacing IIRC, and I've played a few others that are even wider, like 2-5/16". After a minute of playing, I have adapted - if there were a perceptible difference to begin with.
