An interesting story:
In our journey to get the temperature right, we made extensive use of thermal imaging and compared our prototypes with competitors.
The images showed that one of these sensors got extremely hot during operation but the temperature was nearly identical to the real ambient temperature. We couldn't believe this.
So we made a test and put a strong fan onto this sensor. The temperature then dropped by more than two degrees Celcius BELOW ambient which showed clearly that they made a software offset.
It can be debated if such an offset is a legitimate design choice (and I personally believe it has a lot of risks) but it was something we wanted to avoid in our design.

Based on design validation testing, I ended up making the design choice to partially rely on a software offset, a strong fan blowing into the sensor not being a supported scenario. But the placement / air flow / multiple openings definitely took us more design iterations than we had planned for.
