iTunes 8K speculation

What measurements or benchmarks did they use?

If I recall correctly the difference was the BD didn't contain TrueHD audio while the UHD did? It's my understanding that TrueHD is the lossless format on UHD, correct?

BD and UHD both support TrueHD and DTS-HD MA, which are lossless audio formats. They also both support Dolby Atmos, although it's more commonly used on UHD. In any case, the BD and UHD of the Spiderman movie both have lossless audio tracks, so I'd like to know why there is supposedly a quality difference. The UHD additionally has an Atmos track, which is nice if you have an Atmos speaker setup. But then, the iTunes streaming version also has Atmos, so by that metric you could say it's superior to the BD.

I think you're reading too much into what I was referring to? The article was comparing the BRAVIA CORE version of Spiderman: Far From Home to the BD disc AND the UHD versions. Apparently in their comparison the IMAX dts (BRAVIA) was a closer comparison to the BD version in whatever they used to measure...but the UHD disc version was superior, and as I recall they mentioned this was due to the UHD-disc version including TrueHD, while the BD was HD-MA as you said. I gathered from that, that the IMAX dts measured closer (?) to the HD-MA then the TrueHD did?

I don't know or recall how they measured or what they used to measure but their conclusions were the sound was closer to the BD version of the film but was still behind the UHD version. Lossless or not, maybe the HD-MA is not as "robust" as IMAX dts? I dunno?

Picture quality, which they mentioned as well, was on an equal par to the UHD disc.

Lossless is lossless. If there is a difference, it's probably just different levels or maybe a different mix. But in the latter case it would be purely subjective which is "better", and that is certainly not "measurable". Sounds like one of the usual unsubstantiated fluff pieces to me.

Well there were graphs and charts involved, so its obviously more than "subjective"...and it was a study commissioned by Sony. I'm led to believe that because it involved their BRAVIA service and one of their movies. Plus, although I personally read the article in the beginning of June, a week after I got my TV. This article was timed with the introduction of the BRAVIA service as well as the introduction of the newer Bravia TV models and was penned in April if I recall?
But yeah, if you wanna believe it was a "puff" piece, knock yourself out..

It sounds a lot like what you read was an advertisement.

Now THAT seems plausible, grant you that. But since the article I read was only available via subscription...and carries no other advertising, I ruled that out.

But yeah, the structure of the article was certainly pushing the Bravia service, the movie (which is almost two years old now, right?) and the at-the-time coming Bravia XR TV's. The fact I read it 2 mos after it had been published didn't compel me to buy the TV I bought anyway (I bought it the week before I read the article).

Seriously, what prompted me to read the article in the first place (other than just buying the TV they were touting) was the movie using IMAX dts sound, which I thought was the "same" as DTS-X, apparently this is not the case.

I’d rather they focus on losses audio and maybe working with studios and DTS to get DTS streaming someday. Better use of bandwidth. If there is a hole in streaming, it’s the lack of DTS.
