You could confirm this by setting the upload baud-rate and the sketch baud-rate to the same

Setting the upload speed to 115200 just slows down the upload.
The reboot messages as visible e.g. in a wokwi simulation, or after pressing the reset button, and other messages during the first ~400 ms are still invisible.
