Hi Maik,

This is my comparison under my macbook pro M1 running :

- MacOS Somona 14.7.1
- digiKam 8.6.0 Qt6 build at 26 december (arm64 version)
- VLC 3.0.20 (arm64 version)

1/ Playing with digiKam settings: 

- video hardware acceleration = ON
- video textures conversion = ON
- Decoding backend = FFMPEG

HDR video file IMG_1082.MOV (VLC on the left, digiKam on the right):

Regular video file IMG_1087.MOV (VLC on the left, digiKam on the right):

2/ Playing with digiKam settings: 

- video hardware acceleration = ON
- video textures conversion = OFF
- Decoding backend = FFMPEG

3/ Playing with digiKam settings: 

- video hardware acceleration = OFF
- video textures conversion = OFF
- Decoding backend = FFMPEG

--------------------------------------

Conclusion with FFMPEG backend: "video hardware acceleration" must be ON to
prevent washed out color on HDR video. This has no effect on regular video. The
digiKam player always render HDR video as a regular video.

Best regards and Merry Christmas
