Default Can i get my tablet replaced by asus in these conditions?

So, for the last month i can see a purple brush-like dot in the middle of my screen.It can only be seen in dark backgrounds like black or grey.The problem is that in the meantime, i got the hairline screen crack by holding the tablet in my pocket while sitting down, so i don't think it should fall under physical damage since it's more of a design flaw.
Basically if i get my nexus 7 to my local service saying that the tablet has the purple dot problem, can it be replaced without taking into account the screen crack that appeared after the purple dot?
Also, if the screen is broken what parts will i need to manually fix it and will it require some more advanced knowledge?
