I'd assume so as IBZ was downgraded and Sardinia is roughly the same distance.

To be fair though, maybe our expectations are too high. I've flown F in US domestic 3 hour flights and received a small cold salad, whereas the IBZ flight is only 1.5 hours. I always eat in the lounge now rather than relying on airplane food (as there's often the small chance of no meal at al which happened to me flying back from PFO..).
