"The best/highest bit-rate 4K HDR Quality" is going to come from buying the physical disc and either sticking it into a quality player (I use an OPPO UDP-203) or:
- If it doesn't contain Dolby Vision but does have HDR10, ripping 1:1 with something like MakeMKV
- If it does contain Dolby Vision, doing a full-disc backup
If you want the convenience of streaming services like Netflix/Amazon/Vudu and don't want to deal with physical media, FWIW I've never noticed a PQ difference between the Shield and the AppleTV when watching non-Dolby-Vision 4K content. The difference exists (at least with my 2015 Shield) when watching 480p/720p/1080i/1080p content with the Shield and ATV both set to 4k output, and the two upscalers get involved... the AppleTV has a better upscaler than the 2015 (and 2017) NVidia Shield did/does. I haven't purchased a 2019 Shield yet, and have no first-hand opinion on how/if the upscaler is improved and how it compares to the ATV4K's.... at my normal seating distance (12') from my TV (75"), I've always thought the differences between 1080p uncompressed blu ray being upscaled were pretty minimal, but 480p upscaled DVDs were significant. But that's always been "JMO". At 24" away using test patterns designed for the purposes of these comparisons, the differences are easily discernible.
One of the things I prefer about the Shield is it's ability to bitstream the lossless audio to my Receiver rather than handling the decoding internally... but I'm also the kind of person who thinks there can be (subtle) picture quality and sound quality differences between two different CD players or Blu Ray players, too... If you don't buy/rip discs most of this doesn't apply to you.
