I suspect that sometimes TV needs the reboot before it writes that daemon command into the KDE/Plasma AutoStart section. Have you had a look to see if it has now "magically" appeared there? If it has, then that's the likely reason that the problem has "magically" fixed itself. That's what happened to me [i think] with one TV version when i still used Mint 17.x KDE4.
