I'd say it depends. If it was in full compliance with the Code before you add sprinklers I'd say no the sprinklers are above and beyond the MINIMUM of the Code.
If it was not in compliance then maybe. I'd say it needs to be brought up to Code in all respects. Some scenarios require both sprinklers and smoke control, others just sprinklers. Look in Chapter 1 for applicability that I believe is what is the guiding Code section. If it is existing HPS and doesn't have smoke control I'd be first guessing it was not in compliance when built (or changed to HPS).

I looked around in the IFC/IBC/IEBC books, but I could not find anything that would exempt the vents and curtains. Does anyone recall any way to avoid them (other than ESFR)?
