Banding/Posterisation with HDR10 content on Vero 4K

Unfortunately when I play any HDR10 content on my Vero 4K, I get severe banding/posterisation.

My Vero 4K is connected to a LG OLED and all my other media sources are fine when display HDR10 - only the Vero 4K is giving me this issue.

Is this a known issue?
