Give that eq a try and report back on what you think. The depressed 1 to 5 kHz is not good for anyone. Indeed if you can't hear the higher bits, you would want to hear this range.
Done. I've tried this with some stuff I've heard live, classical and vocals because this is probably the most revealing material, but also "rocky" pieces which I know well. Long story short (please remember this is totally subjective hearing based and will probably not apply to you):
First, I've tried to copy your EQ as best I could (with another tool since I don't use Roon but foobar 2000 with its DSP plugin "Graphic Equalizer":
In bass, yes it's better than before, it does sound more like in a closed-back construction, if not quite. Anything more than this is too much. In the midrange, with the emphasis of the above shown range, sibilants of female singers (example: Suzanne Vega, Tom's Diner) sound strangely harsh to me (at normal listening level for me which is -16dB on the RME). Then, for violin and "airy" pieces, the -8dB dip at 8kHz is too deep a dip for my aging hearing, I don't hear the "air" I know to be in the recordings. Both effects are gone with "flattening" the EQ a bit, as ahown below. This sounds just right now and may become my daily EQ, time will show, I always need a few days to tell finally if the new sound is the right sound.
My personal half-educated guess about this: Since every ear is different, and the ear forms a "listening room" with the headphone (filling a much larger part of it than of a normal listening room), probably an individually accurate EQ could be achieved only by measuring the FR in the actual ear, and then equalized for "linearity" related to the (again individual) hearing curve. Like with shoes, size 39 may be ideal on average, but if your feet are 43 it doesn't help much.
