LOL you’re right! Yet, I am still getting no better result when changing it:

<span style="color:#323232;">➤ ~/.config/i3/scripts/qt6ct.sh 
</span><span style="color:#323232;">i3
</span><span style="color:#323232;">qt5ct
</span><span style="color:#323232;">➤ echo "$QT_QPA_PLATFORMTHEME"
</span><span style="color:#323232;">
</span><span style="color:#323232;">➤ ~/.config/i3/scripts/qt6ct.sh 
</span><span style="color:#323232;">i3
</span><span style="color:#323232;">qt5ct
</span><span style="color:#323232;">➤ source ~/.config/i3/scripts/qt6ct.sh 
</span><span style="color:#323232;">i3
</span><span style="color:#323232;">qt5ct
</span><span style="color:#323232;">➤ echo "$QT_QPA_PLATFORMTHEME"
</span><span style="color:#323232;">qt5ct
</span>

Ok, here are very interesting things:

1. I added source ~/.config/i3/scripts/qt6ct.sh at .profile, and logout. When I logged in, nothing has changed. I don’t know why, since when I manually run it, it apparently changes the value of QT_QPA_PLATFORMTHEME.
2. After doing all of that, Qt apps doesn’t seem affected at all, when I open the qt5ct application from Rofi, it keeps showing me the same warning (something like: The QT_QPA_PLATFORMTHEME environment variable has not been set (required values: qt5ct or qt6ct)).
3. AFTER I do all of this, if I run qt5ct or run rofi --show -drun and then select the qt5ct app, then it works just fine. The same happens with dolphin: if I run it from rofi, then it looks awful, but if I run it from the terminal, it looks great. BUT if I close the terminal and open it again, everything goes back to normal (meaning: awful).

After including source ~/.config/i3/scripts/qt6ct.sh to /etc/environment and rebooting to see if anything changed: nope. No changes, the problem persists.
