Water damage: Can I save my phone?

So, my Moto Z Play fell into a pool full of water. After the standard procedure of drying it I tested it and was working! However it had several failures, speakers wouldn't work (any of them), neither the microphone, and from time to time it powered off itself. So I decided to soak it in isopropyl alcohol which solved every issue mentioned before but killed the display (yeah, I know this was maybe not the best idea, but phone was dead anyway and I wouldn't at that time open it by myself to clean the motherboard). After the alcohol bath, I could use it for a while, and every speaker worked properly, so did the mic, and it seemed that it didn't turn off by itself, but an amoled burn appeared, and after a while screen went black. So, my question is, would it be a good idea to try to replace the display module, or would it be just a silly risk?
