Thats definitely a topic in those two videos (I've coincidently watched before), but it approaches it from a sales guys perspective, thats stuck in the sixties.
Basically the "theory" Joe silver offers is, that you should sacrifice everything and anything, just to "impress, fit the situation, or just because it will leave you with a satisfied spouse [his alegories, not mine]".
If you have to put your TV in vivid mode - with PL Gamma 1.9, then just do it, because you want to sell something to a guy driving a Ferrari - or to satisfy your white wine drinking wife and her girlfriends [his mental images for this argument, not mine].
Thats a position. It might even have been a valid one back in the 60s, you being a sales rep at one of those retailers that isn't around anymore - but this coming from the head of the group that is "in control of assessing and establishing color accuracy" - is just too much. And thats before he starts his sales pitch on how to "impress the customer".
F*ck this. Don't give his behavior accolades instead - because you are impressed by a name or a reputation.
The larger issue is, that while this explanation might have been valid 50 years ago - it isn't anymore.
Max. brightness (indoor vs. outdoor "compatible") isn't tied to gamma anymore - hardly at all. The difference in light output between 2.2 and 2.4 gamma on an end user device might be about 30nits on an average scene - on a screen targeting 100 nits. Let it be 50 (it isn't but let it be) - the difference between what SDR content is "meant to be looked at" or "mastered" is 48-72 nits (cinema depending on the projector in use) and 100-120 nits "at home" - to 300-500 nits (full screen white) capability of TVs today.
The "idea" that you'd have to switch to PL Gamma of 1.9 or 2.2 to "get a little more brightness for conventional use" just isn't true anymore -
but thats not my main issue with this freaking sales guy. If you switch from one gamma to another one - you impact color accuracy. You impact look, presentation, directors intent.
Something the ISF was "guarding" by their own volition - but then, two years ago, the industry game along and bought them out, telling them, that the new idea they should be selling was "individual capabilties of max brightness, and max contrast" on a TV.
And the agility with which that freaking guy bowed down to manufacturer interests and went on telling calibrators to sell peak capability (for no real reason - the content for that has yet to be "imagined" and the "standard is in transition") instead of accuracy is astonishing.
As a fact - that guy has no idea - "what gamma to use" in what "room situation" - if he can't escape the question and instead talk about "what brings 30 more, and why that would be beneficial" (in practice it isn't and 30 nits are jumpchange by now). Because his crew, and the industry were instrumental in NOT defining it.
So now the ISF is actively participating in populating the myth that color accuracy is a thing of the past, not important - and if you just wan't to switch to vivid - go ahead, do it - why not. If you can sell more TVs that way - to an unassuming audience....
That sale pitch is in both of those videos. That misrepresentation of the actual role of "the gamma curve" is in both of those videos.
Why I don't know. That guy went on a stage, in front of all "his" calibrators, to talk about gamma and instead talked sales pitches and Ferraris.
Explain that to me (guy - not necessarily you personally).
Joel Silver is my personification and picturepiece of whats so damningly wrong with this industry.
The next thing is, that you - as a manufacturer (lets take LG for example) can happily invite five of those "calibrators" to a product presentation and mess around with "their own" equipment - because in the end you can be absolutely sure - that those guys will come out of that "opportunity" talking about MAJOR IMPROVEMENTS IN OUT OF BLACK PERFORMANCE (something that wasn't on their radar before) - but none of those jokesters will have measured the gamma curve thats responsible for that to begin with.
Then have them talk about "great color accuracy" - because of the new LUT capabilities - but not offer up ANY measurement values on color accuracy. (Just out of interest - compared to what gamma?)
If all ISF calibrators are capable of today is to repeat freaking marketing messages, why do you need them? If they shed the "scientific" principles their discipline is based on at the suggestion of industry initiatives - what purpose do they still serve?
Watch the videos above to get those answers. Upsell. For retailers. Be a money stream for creators of proprietory software solutions. Be part of a feel good factor that suggest "premium" without meaning anything...
Other than that..., I'd say ask Joel Silver - but no, don't...
