3840x2160 with 16 reference frames exceeds Level 5.1 and is not supported in hardware (level 5.1 only supports up to 5 reference frames). If you try, it might work, but it might also result in artifacts. LAV will not perform hardware decoding thats out of spec.

NVIDIA CUVID(old) : OK MPVplayer: OK So is it because the LAV condition is exceeded?

NVIDIA CUVID isn't DXVA2 so it has different limits (it may be more tolerant but it isn't interoperable, you can use it only on NVIDIA cards). About MPVplayer I don't know what it use internally.
