2 engine brake at higher rpm. Around 3500 or more
3 a less than perfect shift
Is this a common symptom for TOB failure? My car has this issue from day one. And it's just a noise issue. Car drives fine.

Are you referring to a sort of snorting/snoring sound under those 3 scenarios? I have the same. The BRZ I rented on Turo did as well. I think it's just the nature of the car.
I always imagined it comes from the clutch springs adjusting under sudden high load of some sort but maybe it comes from the engine... I don't know my stuff so just taking shots in the dark here. All I know is I've always had it as well.
EDIT: under low RPM acceleration, the sound tends to go away around 2k RPM for me.
