"It is a fixed-lens projector, although those lenses are also interchangeable and supports a up to 1.26x zoom."

Make your mind up!

Short throw...I have to assume is not UST, since the projector won't even be able to clear the image if it projects from the front sitting within a meter of the screen. The weight also looks a little suspicious if it's this bright and liquid cooled. Personally I wouldn't touch single chip DLP due to the rainbow effect.
Projectors are truly not in a good position to compete with panels, the future is still μLED. I suspect projectors have less than a decade before high end home cinema is entirely taken over by panels.
