Comment (by Timo R.):
nvenc/nvdec use P016/P216 for historical reasons.
When they were implemented, P012 and P212 didn't exist.
So now migration to those is a bit complicated, since changing the output
format is a breaking change.
And there still is a total lack of support for the 10 and 12 bit formats
that nvdec outputs (and nvenc accepts for input) for 4:4:4, so that's
always mapped to AV_PIX_FMT_YUV444P16, even though the LSB are always 0
(or ignored in case of nvenc).
