I disagree. None of us are privy to the exact nature of licensing fees with these circuits and/or products, and the manufacturers want to keep
it that way. Any guess on our parts is conjecture. The decision of which models will have which features activated, even though the same chip is capable of implementing nearly all of them and they all contain that chip, could simply be the marketing guys' decision to have "good, better, and best" marketing tiers with their subsequent prices and they choose to deactivate some features on some models simply to make there be more incentive to buy the pricier one.
With Dolby Noise Reduction (NR) in the 1970's the way it worked was that anyone could have the chip, anyone could activate it and provide an on off button for it, but only tape decks that paid the licensing fee could use the word "Dolby" on the faceplate or in advertising. JVC made a bold move to see if they could successfully market their tape decks as having "Super ANRS" [automatic noise reduction system] instead, without using the buzz word that sells; "Dolby". They were only partially successful and I think got into legal trouble at one point when their advertising said they were "compatible with Dolby". OOPS, they used the word!
In A/V reproduction accuracy, there IS no concept of "accounting for personal taste/preference". As art consumers we don't "pick" the level of bass, nor the tint/brightness of a scene's sky, any more than we pick the ending of a novel or Mona Lisa's type of smile. "High fidelity" means "high truthfulness", faithful to the original artist's intent: an unmodified, neutral, accurate copy of the original master, ideally being exact and with no discernable alterations, aka "transparency".
