Render the same project in CPU mode.

All the hardware encoders have different "quality" presets that can be used by the software like PD14. It might be an error in programming the requested quality level.

However, I don't expect miracles from h265. Maximum a 20-30% reduction in bitrate without quality loss, when compared to h264.

probably rendered at low bitrate. even with HEVC H.265 you need to stay higher bitrate than

recommended 4K @ 37Mb/sec... for me,

HEVC to HEVC 4K @ 50Mb/sec minimum. it's about equal to 78Mb/sec in AVC H.264 4K.
