Have replaced screen would like to know if its water damage or a poor replacement screen ? As well as the white marks as seen in picture which are only visible on a black background if pressure is applied to certain parts of the screen it will ripple. Any pointers would be much appreciated

IMO, that’s just a bad replacement screen. You should contact your vendor to get a refund or replacement.
