I can't seem to find a definitive answer to this question.
The NR1506 online manual doesn't say, (although the manual for the NR1607 7.1 Ch. Atmos model specifically states that the HDMI inputs support v2.0a and HDR). Richer Sounds say "No", but Marantz Europe Technical Support say "Yes". As I will want a slimline receiver that can support 4k UHD Premium HDR, this information is critical.
