8K+ virtual screen custom screen resolution HiDPI version is not generated (only LoDPI)

[Procisz]

I would need some help, please.

OS: Sequoia 15.5 (24F74)
Hardware: Macbook Pro M4 Pro

I just created my virtual screen with the native resolution (7680x2160), and mirrored it to my Odyssey 57" successfully.
I also defined some custom scaling options, you can see in the image.

I can choose these options well, but only in LoDPI. It seems the HiDPI verison is not created by BetterDisplay.

How can I create HiDPI for that resolutions?

Right, you should go to Settings > Displays > Overview > Additional... > Enable resolutions over 8K.

This is disabled by default as it causes some issues on some configurations.
