I'm glad you've found a profile that sounds more accurate/better to you. I think it makes sense what you say, because the Sample #2 EQ keeps the most energy in the 2kHz+ zone as well as boosting the bass less, so all things being equal it would sound less muffled - whether or not that means it's more accurate & closer to faithful reproduction of the Harman Curve in the case of your particular unit is not too possible to say. However, on average if there was too much energy above 2kHz and not enough bass then it would sound too bright & harsh, and if you're not experiencing that with the Sample #2 EQ then there's a good chance that your headphone is closer to the frequency response of Sample #2, which would fit with my hunch that Sample #2 is the more representative measurement of any Closed X headphone out there in the wild (Sample #1 seemed a little faulty in my view). If you can be parted from your headphone for a few weeks (month+/-) then send it off to be measured by Oratory to be sure, or maybe Amir would measure it, or Crinacle, (Resolve didn't respond to you, it's probably out of his remit to become a source for measuring headphones direct from the community).
EDIT: one extra point, yes, it would be normal that your ears eventually got used to the Sample #1 profile even though you've realised now it sounds veiled - our brains quickly adapt to the sound of a headphone to normalise it......that doesn't mean you can't get better sound by using a different EQ, it just means you have to compare them side by side in a listening session to find the one that sounds the best, and then that's the one to use. (If you've got some anechoic flat reference speakers to listen to as well then that can help you realise the intended tonality to aim for too on your well known tracks, albeit it is quite hard to compare headphone tonality with speaker tonality on a practical level, but it's another data point.)
