Taking a bit of flak here Barry!
Don't let it get to you mate it's all friendly.
First up,
Video quality is important to me.
Trying to play the "can't we all just get along" card, just this once, I'll put forward this, and ask you to have a think about it.
Some people prefer a brighter picture on their TVs, others turn the colour up to make it look "richer", because it's their preference.
That's the subjective part?
Conversely: There are facts that are facts...that are facts...as I think your alluding to.
For myself, OLED was a gamechanger.
Some things are just better.
I've had mine ISF calibrated and yup, the pictures better for the calibration.
After calibration though, I was presented with a choice of 3 profiles, to accommodate my preferences, which I found interesting.
So I hear you on the picture calibration and standards.
Video quality and preference is subjective just as with audio IMO.
For music..."Is it like I am i sitting at the recording desk listening to this?" or "Feels like I am in the 4th row at a live gig!", usually works.
But...there's no universally subjectively preferred way (by all) of viewing video.
Again, that's the subjective part...
Can't really say it's unfair to say that colour grading in movies can completely change the experience of seeing the same film?
How many "Director's cuts" and anniversary reissues were put out where the picture was messed about with (grain removed, colours enhanced, DNR applied...etc) to outcry by the "purists"?
Crikey, just look at the Star Wars reissues with updated SFX!
but I'd ask the question - One can say this is the best picture because its "calibrated" - But I'd ask...the best to whom?
Only thing that matters to ME is how something performs...in my room...with my eyes...with my equipment.
No disrespect, but have to disagree with you one important point:
Its my opinion that Video
IS subjective - just like audio!
It's the brain interpreting inputs, thats all it is. Same with music.
My point, if there is one
, is that the calibrated "standard" was created by people who CHOSE those settings,I'd ask you to contrast that with the nebulous concept of "artistic vision", bringing in aspects like colour grading, cinematography and the like.
And interestingly...and to your point...
Trying out different HDMI cables and finally settling on the "one" for me with my AV kit, I was able to clearly see these differences - and
the differences the way different HDMI cables presented them.
...for the record.
