Your best guessing suggests you have not.
Perfect copies of the autographs. However I was mistaken about there being no variation. There is some at 1:16. So I would have to modify John 1:1-15, 17.
Ridiculous.
It is not an honest way to look at it at all. Between the Hodges/Farstad Majority Text, Pierpont/Robinson Byzantine Text, and Pickering's Family 35 there is 99.5 % agreement. Textus Receptus 98% agreement, and even Nestle/Aland Text 96% agreement.
You think there is any doubt about having the Originals when in the places all of these Greek Texts agree 100% , which is the vast majority of the time?
