FWIW I don't think the Q701 is bright (modded versus unmodded not relevant in this aspect). I'd say there's a very slight bleach to the tone in mid/top, so very small that I noticed it only when comparing to SOTA phones, but that is not the same as bright (which I define as too much treble energy compared to mid).
If there's too much treble being perceived, perhaps you should look upstream? Also, switch mode power supply noise can cause a bit of glare, depending on the system being used. Any problems upstream might bite with cymbals, electric guitars, things with lots of harmonics like that.
