Comment (by yigithan):

 With some research, the problem looks like to me "Tone mapping". I am not
 sure I am still trying to figure out but it looks like default
 {{{videotoolbox_vld}}} making basic tone mapping**?** during hardware
 decoding and if specify the {{{pix_fmt}}} in this case the **format =
 **{{{p010le}}} which is 10 bit format, It looks like it supposed to be.
