The three things I spotted were hangar bay has a fin type thing above it, there’s an extra bit on the rear of the “neck” from saucer to engineering hill and the position and rake of the pylons is shorter on the Nemesis version which brings the nacelles forward a touch and opens up the rear of the engineering hill a bit.
Bottom ship doesn’t have the same body profile on the bottom of the main body (engineering?)

A little fin, shoulder pads, and a bit more junk in the trunk.
I Magic-Eyed it and saw the same things. Fin, hunch back, and shifted pylons.
