There was probable less parity within conferences but some conferences have been lopsided lately too. As far as national parity, that is a good question.There was a lot less parity in CFB then, yes. You could say about them same thing of any teams that were dominant in those eras.
Let's use the 8 CFP years and go back 30 years using final AP poll since we didn't have CFP or BCS selection type process.
CFP Era
32 slots available with 13 teams represented. Bama, Ohio State, FSU, Oregon, Sparty, Clemson, Washington, Oklahoma, Georgia, LSU, Michigan, Cincy, Notre Dame.
1984-91

1991 - 1)Miami 2)Washington 3)Penn State 4)Florida State
About the same as far as "variety" goes. So national parity may have been about the same. We'd probably have been hearing about Miami, Florida State fatigue for a few years like we have with Bama, Clem, Ohio State curing the CFP era....had such been in place.
Noticeably absent from the 84-91 list are USC, Ohio State and Texas. One would have thought at least one or two of those "brands" would have finished in the top four during that eight year stretch.
