Itunes movies no hdr or dolby vision
Hi everyone, I have purchased a few movies from itunes today, all 4k dolby vision, yet my tv is only showing it’s displaying 2160p, no dv logo. Im pretty sure I have everything set up right as everything works perfect using prime video and netflix apps, hdr or dv logo shows straight away on my lg c7. The atv menu screen is hdr, just not itunes movies?! Anyone else had this? Thanks in advance.
