This utility does the ONLY two features I found useful in the ridiculously bloated BetterDisplay app.

1. It fixes HDMI 2.1 displays somehow falling back to lower bandwidth and without HDR support.
2. It switches any YCbCr color modes to RGB at the highest bit depth if available.

That's all it does, there are no other features.

I have no idea what MacOS versions it's compatible with, but it's made for MacOS 26
