Ok, thanks! This clarified the issue. By the way, I think my DT48 (200 ohm) is extremely transparent phone. Much more realistic than AKG 501. The latter excels only in highs and producing concert hall like acoustics. But there is also something artificial in K501 that is not present in DT48.
I think DT48 is very accurate for soundscapes, where only one mic was used for recording. It is way too revealing for watching movies. For example, in "The Master" there is a scene where a girl sings in park. I could immediatedly hear that her singing was recorded later in studio and dubbed. It is weird to see character singing in park, but clearly hear there studio walls
Usually I recognise dubbing from sync issues.
Similarly, one can sometimes hear that typical modern classical recordings are mixed from multiple mics hanging very far. K501 sounds more "realistic", because music appears as if it would be coming from concert hall. Hence it is not that DT48 could not handle large orchestral pieces, because it certainly is able to do that, but it sounds better with chamber music and jazz, because there are typically fewer mics distorting the impression of space. Those ascetic recordings and some little bit older recordings may sound extremely realistic.
