We currently use the Boeing OPT iPad app for our performance figures on the 787-9 and apart from V speeds and flap settings, all engine and engine out target pitch attitudes are calculated.
We do rotate TOWARDS 15 degrees, but will end up at the calculated attitude on speed if our rotation rate was correct.

Interesting. I am maybe forgetting now, but I don't recall this on any conventional type I have flown - even the B737 Classic. It was always a set pitch. Those aircraft were not the size of a B747 though.
Airbus FBW presumably does use the aircraft mass to calculate a pitch angle for the speed bug and the SRS, speed reference system, to achieve V2+10? But it does not display it as an actual figure for the pilots, who rotate to +15° and when airborne they follow the SRS in pitch.
