You use the truss-rod to get correct relief...not necessarily "perfectly straight"...oftentimes (depending on the player, technique, strings, etc.) this means a slight forward bow.
After that, you make changes to saddle and/or nut height.
The "final conclusion" (IMO) is that no one on the internet can diagnose what, exactly, is happening with your guitar, and with the failed set-up. Only by having the instrument in-hand and on-the-bench can any tech/repair-person (qualified, hopefully) bring your instrument to proper-playability for you and your technique.
The mixed information you are perceiving relates to the mixed amount of knowledge folks have within any diverse group.
