So after thinking arround the corner I think you wanted to say: https://en.wikipedia.org/wiki/YCbCr the decoder is able to decode formats using that color model (be it used in the YUV way or else) without any loss while decoding. And yes this i right. The decoder does a good job.
Now comes the troublesome part: We have no influence onto the decoded data. It is output like they want. No influence on BT601 nor BT7019 - we can only hope it does the job right. Furthermore when target system is a full rgb monitor, something needs to be done or banding is introduced when scaled to full or blacks and whites are not existent.
Especially the last part is critical in playback world.
