I've also observed the NEO speeds are slower. Still trying to figure out why. The first picture is uncomfortably slow, but I'd do it if requested by ATC, and if the environment permitted.
I would not be as slow as your captain opted to fly in that second picture. The computer can spit out whatever CI it likes, it's still my butt strapped to the plane up there. If it all goes wrong, not much the computer can do to help.
