Turns out the planet is a true "hot Neptune" with a hydrogen envelope instead of a some sort of ocean planet speculated.
So it will be basically hotter brother of Neptune in our Sol system; even apparence will be almost the same because that planet is too hot for watery or acidic clouds but too cold for sodium haze or silicate clouds so the planet is blue.
Clarified Neptunian
