I checked out a couple of those vids and looked closely to my oldest acoustics.
So fwiw, I have a 2008 RTaylor, style 2 (GC size body), and I can just barely see two lines of this "telegraphing" (that I've also heard called "witness lines") in the top near the sound hole. And I mean just barely visible if the light angle is exactly right and reflecting just so. Keep in mind this guit is forward-shifted X bracing, but these RTs were very lightly built/braced, and also purportedly had a thinner finish relative to the production line Taylors of that era. All to say I think what you're seeing is simply a matter of the guitar's build parameters and, as the factory stated, variances in RH. Mine is simply old and been played lots. Rock stable in all ways so I never noticed it until you brought it up. If it ain't causing you issues, enjoy it!
