I forgot a display signal doesn't include any alpha channel, so yeah 8 bpc will require less bandwidth than 10 bpc.

The maximum capability of the monitor should be advertised in its EDID. At least modern monitors do. You can check it using the 'edid-decode' command and grepping for 'bits per primary'. What gets returned?

Can you share the EDID of the troublesome display?
