Naa, I'm not wrong, I know what I'm experiencing, maybe terrestrial TV in the UK is different somehow, but in general here the TV and movies have reduced high frequency in comparison music in my experience. And you're also wrong about the target curve for most movie making, it's not high frequency rich. AVR's probably have "Cinema EQ" to reduce HF because as I said a lot of movies have been recorded with something close to an X-curve which is high frequency poor, so the "Cinema EQ" effect is just to reproduce the "Cinema Feel" of reduced HF.Well, your "research" is wrong. As I said, movie audio tracks have boosted HF as theatres tend to absorb them and for that reason most of the AVRs have some kind of "cinema EQ" to reduce HF on the movie tracks to avoid it sound hursh and with accentuated sybilants.
Just now I did have switch to my Half Harman curve for watching a documentary as the HF was piercing my ears of my "Flat Curve", but again it's not a full on Harman curve. Looks like I'll need to switch between Half Harman Curve and Flat Curve depending on what I'm watching.
EDIT: did a bit more research on "Cinema Sound" and X-Curve, Amir did an article on it: https://www.audiosciencereview.com/forum/index.php?threads/validity-of-x-curve-for-cinema-sound.204/
It was concluded that X-Curve does not sound good and takes out too much of the high frequencies. Another conclusion was that theatres do not follow the X-Curve naturally from an acoustic point of view...ie the natural high frequency roll off is nowhere near that described by the X-Curve even though it is part of Dolby accreditation standards. My take on this...is that therefore movie soundtracks are often produced with reduced High Frequency emphasis because this would make it easier to EQ the content to the X-Curve in the movie theatres...because it's already been concluded that the acoustics of movie theatres do not reduce high frequency content by anything like the amount that the X-Curve describes. So I think this backs up my experience and conclusion that movie content is not recorded/produced with an emphasis on high frequency content, it's probably actually produced with a de-emphasis on said high frequency content in an effort to more accurately fit the "unnatural" X-curve.
