Hidden/Inaccessible Chess Piece Set Found!

Hello all! I noticed a different piece set while scrolling through the homepage ( chess.com/home ). These pieces look like a mix of Neo and Modern piece sets. Upon clicking both daily puzzle and game of the day, it would just redirect me to play mode and have the usual neo + green theme. I am so curious as to why this piece set isn't accessible in live/play modes. Also I wrote to chess.com support, but they just say use Neo + Green, what a joke!
PS I have tried using various browsers like Firefox, Chrome, Safari and they all show this. I'm on MacOS 10.13.6 High Sierra.

It's just the gif that shows. It's for display only.

Ah! But the pieces look very Neo like. As in it seems like its an actual variation of the neo set.

I wonder if you know the name of this set or got the userstyle for it??

I see a checkmate in one. if black takes the knight with the queen, it is a checkmate.
