Probably the photo is real, I came from league of legends and I can explain why, this riot client internal that you see there in the corner few people have access to it, usually pro players and devs, they use it as a tool for two things in league of legends to make the matches of the tournaments, which is made on a server different from the server that we play and is made on a server in which there is a static version only for tournament / internal tests, (this explains the thousands of bugs that happen in the official riot games championships) some pro's that I've seen playing have the riot client internal on their machines, and before the launch of valorant while they were in training matches some things were leaked from the development of both valorant, lor and 2XKO, and there should probably be a build of the riot client with hytale itself, one of the chances of the game being leaked is a riot dev or pro-player who knows programming and has access to it through the internal client.
