Original GitHub issue: https://github.com/games-on-whales/wolf/issues/249

Launching any application (ES-DE, RetroArch, etc) via a Moonlight client on a LG TV, everything gets a strong purple palette in place of the normal color field.

This does not happen if from the client the options for H.265 and AV1 are disabled, but going straight via TV hardware decoding makes performance extremely bad.
HDR option (enabled or disabled) is not changing anything.

Color palette is correct accessing the same server on a different client (for example via Moonlight on Windows).

As a workaround, after some tinkering with the config.toml, I found that forcing the color space by changing from

[gstreamer.video.defaults.qsv]
video_params_zero_copy = 'colorimetry={color_space}'

[gstreamer.video.defaults.qsv]
video_params_zero_copy = 'colorimetry=bt709'

solves the problem.

Can you provide the debug Wolf logs with the env variable WOLF_LOG_LEVEL=DEBUG to see exactly which color_space is requested by the Moonlight TV client (you'll see the resulting Gstreamer pipeline in the logs if you leave colorimetry={color_space})?
I feel that this should be reported upstream to https://github.com/mariotaku/moonlight-tv Wolf will just match the requested color space.
