Confused HDR Newbie Looking for Clarifications....
I searched high and low for a good sub-forum to post this but none seemed to be an exact fit, so if this is off-topic or covered a million times (I did search for similar posts, but didn't find much) I sincerely apologize and mods, feel free to delete post and ban me for life. :-)
In any event, new-ish owner of LG C9, so can watch movies w/Dolby Vision, which is awesome. So here's my confusion:
1. Apple rents/sells movies labeled as "4K" and with HDR. But if you look at the details, many (older) titles are in 1080p. Obviously, much depends on the source material but....is 1080p with HDR truly 4K? Or merely HD with HDR, and Apple is lying about 4K?
2. I bought the Blu-Ray/UHD Top Gun DVD, and I can play it on my XBox One X in 4K/2160p, but without HDR (bc XBox doesn't support HDR). Or, I can play a downloaded copy of the movie (DVD came with redemption code) via AppleTV+ app on LG, with HDR, but only in 1080p. So all things being equal, is 1080p with HDR "better" than 4K rez without HDR? To me, the AppleTV+/1080p/HDR version of Top Gun looked as good as, if not better than, the 4K DVD on the XBox. So maybe I wasted my money on the Blu Ray disk and should have just purchased the movie from Apple?
4. Or, to get the full, best experience should I get a dedicated Blu Ray/UHD/4K player that has HDR support? Especially to view older movie titles that have been converted to 4K and/or HDR and are on Blu-Ray (ie, that Apple doesn't offer in 4K resolution). With streaming becoming the standard delivery method these days, though, spending several hundred dollars on a Blu Ray player seems like buying a VHS deck......
In any event, I am clueless about this topic so hope at least some of my questions make sense and a kind and patient soul here can help.
