I had a nice copy of this comic but had no idea what I was selling when I let it go.
Yep, this wasn't always considered Darkseids first full appearance. OPG always had it as such, but CGC called it a cameo. He's not on every page of the book, but he's in it enough. 6 panels I believe, spread across 3-4 pages with plenty of speaking. He plays a slightly larger role than Gamora in ST 180, which is considered her first full. When its close, sometimes picking up a reader and doing some due dilligence can make a world of difference.
Here's my old school copy showing exactly what your talking about:
