When creating a warlock with Pact of the Tome or a patron that grants extra cantrips and spells, these spells are not granted the bonus to hit/DC from a Rod of the Pact Keeper. The rod only applies to cantrips granted through the warlock spellcasting ability directly.
The rod's description states
"...you gain a bonus to spell attack rolls and to the saving throw DCs of your warlock spells".
Pact of the Tome states:
"...If they don’t appear on the warlock spell list, they are nonetheless warlock spells for you".
The warlock Celestial patron states:
"At 1st level, you learn the light and sacred flame cantrips. They count as warlock cantrips for you".
Expected Result:
Given the item and ability descriptions, I would expect the bonus to be applied to spells gained through those abilities and any other ability that states that spells are "warlock spells".
Rod of the Pact Keeper is supposed add a +1 to my spell attack and save DC for Warlock Spells. It works for my chosen spells, like Elderitch Blast and Thunder Step, but doesn't work for Light and Sacred Flame, gained from The Celestial subclass, or for cantrips like Shocking Grasp gained from the Pact of the Tome feature. My understanding is that both of these groups of spells count as Warlock spells, but don't seem to be tagged that way for the Rod of the Pact Keeper.

Only spells picked directly through the warlock class will have the bonus applied.

This might be an issue for other classes with similar items and options to get extra spells.
Bravo on a well detailed bug report. Too often I see "Rod of the pactkeeper doesn't work" or equivalent with little or no other details.
This bug has been reported before. I think it is expected to get fixed in next character sheet update (whenever that will be in the nearish future).
Occupational hazard of being a software developer, I guess.
Looking forward to seeing it fixed.

This bug has been pushed to devs already. I think they are going to fix it in a (nearish) future update. If they don't, we will keep reporting it...
