Dull colors in 4K on RPI4

Good morning

I'm on libreelec 11.0.1 via an RPI4 and a 1080p video projector

When I display a source in 4K the image seems perfectly sharp but the colors are bland, even slightly greyed out. (no problem un 1080p source)

I tried quite a few options to try and fix this but nothing worked. I remember a few years ago not having this problem with earlier versions.

Does anyone have a solution?

If the video files are HDR and the projector doesn't support HDR, then the colours will be wrong.

This has never worked on a Pi.

Could it be that it comes from Dolby Vision file? Because on the Matrix version I had no problem on 4K files

DV files won't play right even if the projector does support HDR. DV media is not supported.
