Nope, ATV/Mac do not support DV unless you count gimmicks like HDR400/600/800 as proper "HDR support", they only support profile 5 and cant even play a profile 7 even without the FEL layer, making them largely pointless, read my previous post for more details and sheet I linked for hardware compatibility reference but the Tl: DR is profile 5 is mainly used by streaming platforms like Netflix, and profile 7 is mainly used in UHD blurays.
Now this is where we start getting into the classic audiophile discussion territory.
There are folks into audio who can spend hours trying to convince why even lossless encoding like ALAC doesn't compare with a raw audio stream.
As far as I am concerned, I find it difiicult to tell between even lossless and high bit rate compressed streams despite having audio equipment that can handle a much greater level of detail than the average consumer grade equipment.
Similarly on Blu Ray vs streaming (lets leave encodes and remuxes out for a bit), my personal take is that anything over 40mbps /hevc main10 /DV or HDR10+ gets visually indistinguishable from a physical disk.
Now coming to your point on profile 5 vs 7 (or even 10/20), why does it matter to me as an end user?
SDR-> HDR was a massive visual jump and HDR -> HDR10+/DV (regardless of profile) for me has been a small incremental jump
Chasing a higher profile on DV at least to me is pure specs chasing for an end consumer.
FWIW I find DV playback on ATV fantastic (and also a noticeable jump up from HDR) - and it manages this without any fuss/drama/tweaking for everyday usage wit the click of a button - Thats all I ask for now till something
noticeably better comes along . The last such major improvements were DVD->1080p (huge) >4k SDR (nice but not as much as touted) -> 4K HDR (huge) -> 4K 10+/DV (small but noticeable)
yeah, thats fine for a normal user but I am really into archiving remuxes, Remuxes are the best way to view any movie (atleast the good ones) where the encoder has selected the best video tracks from different region BD releases, synced audio/subs, made sure to pick up the best audio tracks and added in support for backwards compatibility, added chapters etc etc, you literally cant find a better release legally than some of the remuxes available. for e.g this is for a top gun maverick remux
This is where your use case starts differing from a regular end user pursuing a convenient way to handle playback without compromising on quality .
You would fall under the category of a collector which is a legit hobby in its own right
The discussion on this thread, if i am not wrong is how transcoding is an important consideration for a home server in 2024 for a general user like I
if you are depending on Mac/ATV for your DV playback and your monitor only supports HDR800, then its just a placebo. in your words you are padding a size 10 shoe to fit your size 4 foot, get atleast a proper QLED display if not OLED with proper dimming zones to take advantage of DV/HDR.
Kinda like you, i like collecting equipment.
Audio first but of late video as well - and while my video setup is not at par with audio but it does include:
- LG G2 (Evo OLED, 1000 nits),
- 85 U7K (fairly bright mini led with high number of dimming zones..not sure what the peak HDR brightness is but it does get eye searingly bright, more so than the former)
- a couple of 1600 capable Macbooks (which i presonally find the best in terms of video capabilities)
- a 1000 ipad pro
- a Samsung s8+ oled (which honestly is quite sad, display-wise)
- a benq 3280 monitor (maybe its 400 or 600 - cant rememebr but it does act as a lower baseline for comparison)
I also enjoy doing AB tests on both audio and video So I would like to believe that my comments so far are based on real life usage and not based on second hand info collected from YT review or comments on the interwebs
