Who said it was less compliant? Compliance has nothing to do with a device's compendence and picture quality. Are you suggesting all LG and Vizio TV are superior to those made by other manufacturers? If so then it isn't relected in the opinion of most reviewers. Most content isn't going to be encoded using Dolby Vision so the ability of a TV to display such content not encoded with Dolby Vision compared to other devices is more important than its Dolby Vision compliance.
Both DTS-HD Master Audio and Dolby TrueHD are optional audio formats and neither is mandatory or awarded any preference as far as the standards are concerned. I'm not here to argue with someone on points that have no bearing and are technically incorrent. If you are going to throw something into the equation then at least make sure you know what the facts are relating to it.
Once again im not here to argue a specific TV, if i were to guess based off your comments, your just butthurt that you bought an expensive 4K TV too early. I am commenting on the HDR format specifically. Which is better and you have yet to give any facts to say HDR10 is, besides LG isn't superior. 10 bit vs 12 bit. nuff said.
LGs are pretty good too, did you buy a Sony?
You may say that TVs aren't yet capable of displaying such high goals,
True, but why cap yourself at 10 bits. its like shooting yourself in the foot.
And before you say it can be upgraded, just like dynamic metadata has...
True, but if it has to use HDMI 2.1 that's a pain in the ass
didn't mean to confuse you about DTS either, i know its not technically the standard but if everyone uses it over TrueHD and every inferior codec i think i made my point as it was intended.
Once again this is about HDR and not TVs as they will evolve where as HDR codecs will probably not, until HDR12 comes out and you need 2.1 connections to be just as good as Vision.
Ill end with saying im not advocating a proprietary codec, I hate apple, for this and other reasons. That said, if its better im going to be for it. Thank god lighting is not superior to USB type C
