Coversion Dolby Vision to SDR

[Selur]

Yes, there is no option to disable or enable gpu support:

placebo.Tonemap(clip clip[, int src_csp, int dst_csp, int dst_prim, float src_max, float src_min, float dst_max, float dst_min, int dynamic_peak_detection, float smoothing_period, float scene_threshold_low, scene_threshold_high, int intent, int gamut_mode, int tone_mapping_function, int tone_mapping_mode, float tone_mapping_param, float tone_mapping_crosstalk, bool use_dovi, bool visualize_lut])

so its probably using whatever it finds.

As a side note: TimeCube also has matrices for dvhe0509.
