There was a large (and expensive) test suite of encoded files and checksums that we had at Broadcom.
I would expect other hardware codecs to have similar test suites and to get the rounding right,
so I'd be surprised if it is common to get this wrong.
As you say, the YUV->RGB conversion is something more likely to be got wrong.
But it's fairly easy to test this with a calibration video and a hdmi capture card.
