Not necessarily, since you have nowhere agreed to these in lieu of compensation. PS to main is likely more of a difference, though you may also need to fight them to get more than the PS you paid for to Y-day-of difference they're likely going to offer.
Do the EC261 calculation and see if it's worthwhile and still put a claim in.
There is also the question of compensation vs simply difference in fare that needs to be refunded anyways.
