Converted project from PR 2020 to 2022 - LUTs working differently?

Hi everyone, weird issue I'm encountering.

Today I opened a project previously saved in Premiere 2020 v14.8. It converted to the version I currently use - 22.6.3. But Input LUTs on footage are suddenly super saturated and look odd.

Output from original project:

Screengrab from converted project:

Footage was shot with a Sony A7, file format is mxf. LUT is a .cube file. Any ideas why this has happened?
