Reference 20-N Restoration of Lineholder Lost Day Off:

20-N-1 When a Lineholder is reassigned into a day or days off under the provisions of Sections 20-F-2, 20-I-5-a, 20-I-12 (Step Seven), 20-I-13 (Step Eight), or 20-J and his schedule does not require a repair due to the Minimum Day Off provisions of Section 5, that day or days off shall be restored according to the provisions of this Section 20-N.

The bold section above is the key. Your DH back to base does not fall within those parameters as reassignment.

However, you will get:

20-L-6 Add Pay for Reassignments
20-L-6-a Late Pay. A Lineholder shall receive fifty percent (50%) Add Pay for all scheduled Flight Time and Deadhead Time after his original Arrival time.

20-L-6-b Day-Off Pay. A Pilot shall receive fifty percent (50%) Add Pay for all scheduled Flight Time and Deadhead Time on a day off (regardless of whether the day off is restored).

Scheduler is correct and recent response to a PDR confirmed this with the above referenced sections.
