Interesting. It seems a bit counter-intuitive that different values would have the same output, outside of limited-range clips

...but how can a decoder possibly differentiate between a 10-bit HDR clip and a 10-bit clip from the video standards? I seems to me like the standards conflict; e.g. a HDR clip would assume 1023 != 1020 but if decoded as a "standards compliant" clip the white point would be clippped to 1020.

Edit: Granted, none of this matters if you're only using 10-bit to reduce quant error, but it's interesting nonetheless.
