That's pretty good! Boards seems to run pretty cool..
There is not much of a droop with such a short wire and the 0,091v difference between cool and warmed up means the case temperature must be pretty low. Maybe 40-45° or so...
Your driver is CV/CC version. This means it can work in both modes constant voltage and constant current. The CV mode is only active with additional DC to DC drivers like Meanwells LDD's or when you set the voltage manually higher like the nominal voltage of the driver(voltage adjustment range, A version has voltage and current regulators below the small rubber plugs)
When directly connected to LED's the driver works always in CC mode and the constant current region is in use. The voltage of the LED's connected must fall within this range.(18-36v)
Only if you use LED's with a slightly higher voltage (lets say 38v) you need to set the voltage higher via the left vF regulator. In this case the voltage is above its CC region and the driver is forced to run in CV mode.
Your voltage fits perfectly in the CC region so you can be sure its running in CC mode!
Thats the corresponding part of the datasheet. Looks meaningless but it is very important to understand how these drivers work...

Your driver can run in CC mode with LED modules with a voltage between 18 and 36v. It would only work in CV mode with DC to DC drivers or LED modules with a voltage between 36 and 38v.
