Listen without letting it burn in for any longer - it will show whether the sound changes noticeably over time.
Fleetwood Mac, Songbird
K812 stage a bit more spacious
DT1990 ~8 kHz peak is also noticeable with normal female singing (not just with sibilants), if you listen carefully and know what to pay attention to.

Pink Floyd, The Final Cut - 2 different CD mixes
Tr.1 The Post War Dream
The jingling of coins is clearly audible.
.
Tr. 12/13 Two Sets in the Sunset
Hissing of the drums (brass), natural, pleasant - as I know it live!
--
In between for relaxation
Joe Zawinul, My People
One of my absolute favorite pieces on this album “Erdäpfe Blues” (Potato Blues). Deep bass hits.
There's a real live character coming through, bass as it should be!
No sharpness in overall voices.
Very pleasant and relaxing to listen to!
--
Nachtfahrten, Nachtfahrten (Night driving, night driving)
Drum beats strong, powerful, but not too “cold” (if real deep bass is missing).
--
Mystical Scent, Sacred Book
Abyssally deep, powerful bass - if not as deep as the Denon AH D7000 had at the time - but it was closed and had an unpleasant bass hump towards the higher bass frequencies - so I ultimately sold it.
--
So Spoke Zarathustra, Richard Strauss
The deep organ tone at the beginning is clearly perceptible.
--
Back on the block, Quincy Jones
Prologue, Back on the Block, The Places You Find Love, Birdland, Prelude To The Garden, The Secret Garden
I really like the vocal range of the singers, more fullness in the expression!
--
Wia Die Zeit Vergeht (How time flies), Hubert von Goisern, live
Disc 2 Tr.5. Kren & Speck (~10 min) - drum solo from ~4:00
Hard hits, drums and woods against each other. Live character.
Comparison - the DT1990 is missing something in the middle range, the K812 sounds a bit hollow - don't overestimate it, these are my impressions and they are at a high level.
Voices and instruments always well separated, as long as the recording itself is OK. K812 seems to have a slightly bigger stage here, but is weak (at a high level) in other things.
For the very first playthrough, some tracks were only played briefly, composer tuned very well!
Now the system is being rebuilt and Full Score One is being ground in.
