So I do not believe that the car has reduced HP before the re-flash.
Agreed, a lot of so called dealership techs don't know what they are talking about. When I took my X5M in for the first time, they wanted to put 10/60 in it, I told them shouldn't it be 5W-30? The tech said no, all M car uses 10/60, I then showed him BWM's own documents that says X5M should use 5W-30 and the tech apologized and said he has never seen the document.

I don't know whether BMW F10 M5 has reduced HP before 1200M service or not, but I do know techs are not to be trusted completely.
