Q: iPhone water damage, can i still get a replacement?

So my iPhone 6 had a dead pixel, i arranged an ERS with apple and the iPhone was just dispatched yesterday morning (it was supposed to arrive on Tuesday, very late.), anyway i was told by apple that i should remove my screen protector, case and disable find my iPhone, i had a new case and screen protector waiting for my new phone so i didn't open it and it would've prevented the damage since it covers all in inputs unless opened, i was on the phone and the phone slipped and landed right in my cup a few days before i would've received my replacement, so i cancelled my ERS explaining what happened or else id have to pay a lot of money. so my question is, if my iPhone still powers on and i can show them the dead pixel will they replace it? i understand by EU law any hardware issues that its shipped with have to be replaced by law, but is this now VOID because of my accident? on my behalf i can express that if the ONE dead pixel was due to water damage, it wouldn't be just one, for a drop of water to get to the screen would cause more damage than just a single pixel, thoughts and advice please! this is a very sticky situation and i hope apple will be understanding
