I'm watching Encounter at Farpoint now and I'm noticing a lot of things they established in the first episode that they changed or ignored later.
1) Holodeck rear wall
They never really explained by holodecks can reproduce seemingly infinitely large environment. Many have imagined it's a series of light illusions and treadmills, which makes sense given that in literally any other episode being in the holodeck pretty much means an infinitely large completely convincing fake world. Also Data remarks that much of the material in the holodeck is actually real much like it was created via the transporter, whereas in the future it's all forcefields and light.
2) Riker can hear Troi's thoughts
The writers either didn't like this and handwaved it or they forgot about it, much like Vorta telekinesis.
3) Starfleet = Humans
Troi "My mother was betazoid. My father was in Starfleet." A crewmember from later in TNG or any of DS9 or Voyager hears this and still probably thinks her father is betazoid. Starfleet was mostly a strictly human organization at this point, and alien presence was an exception. It was not just the military of a truly interstellar alliance.
4) Q is weaker
Q is not quite the same level of omnipotent here. He is concerned about getting stunned by Torres on the bridge. He must chase the ship in order to use his powers on them.
5) Geordi could perhaps restore his sight, through an operation that he is nervous about.
He does not want this operation because he is an advanced human and the blindness is who he is. I suppose this is realistic, a lot of deaf people refuse cochlear implants for fear of losing their identity. But I don't see later series Geordi refusing the operation.
6) Ferengi eat people.
Uh huh. I suppose this isn't necessarily a contradiction, maybe the Federation really believed this because they are evil capitalists and stuff. And at this point all the Ferengi they ever met had horrible spinal disorders and speech impediments.
7) The Enterprise D is exploring deep space.
They are out in unexplored space, far away from local Federation politics.
