Whether or not the possibility was there already on the sharkletted CEO's but such testing was not done or not explored for commonality purpouses is a speculation squared.

A nice find. The Vmca is higher on the -271N, green dot as well if only by a little.

F and S remain identical, while Vls CF3 is higher by 2 kts, that is somewhat perplexing.
Nice catch, I am checking CFM/CFM LEAP data and the VMCA is 4 kts higher on the latter. Other than that, I only find a significant difference on Vref between CEO/NEO as discussed above, ie. 6 kts lower on the NEO, but that is due to the higher flap angle.
