How can I recreate legacy lighting?

A while back i found this ColorCorrection on the devforum which helps recreate Lighting.Legacy’s vibrant colors on Voxel+

The issue with this is it needs Voxel which adds stuff like SSAO and is less performant. I want Compatibility (closest to Legacy) without the weird color issues. Is this possible?

SSAO (now HBAO) has been around since 2010, you can’t get rid of it.
It only appears at the maximum graphics settings.

It doesn’t appear in the same way with Compatibility
I think Compatibility still uses the old algorithm for it which isnt that noticable
