You mean specifically in this room?
I'm afraid you won't find anything special here apart from the "beautiful" decoration and a little bit of lore to read.
But i have to admit it's a shame, this room could have had at least two good scenes. One with the "magical" pond, mabye drink some of it and either die from whatever it does to a human or maybe get some kind of transformation, like in the second game. Her sister could even have a slightly different reaction, maybe a brief moment of shock.
Or another scene involving the big insect broodmother thing on the ceiling, that would have been great.
