Hi!
I don’t own pop3 but pop2 and miraco (next to pop1, mini1 and range1). Pop 3 is some more improved version of pop2, especially regarding IMU (helps with tracking) and optical zoom for better scanning of tiny details (also giving crispier edges). Otherwise they seem to be comparable regarding scanning abilities of black surfaces due to IR projector tech.
POP 2 and Miraco perform similar on mid size objects, miraco is better on smaller objects. You can compare the specs on revopoin’t homepage. POP 3 should give you at least the same results as miraco on small to midsized objects.
The scan was done with miraco without any spray , but my car was in the garage with very little sunlight from the outside. Still the pedals are in the shady space any themselves, so I wouldn’t worry about that even if you cannot move the car - but the shadier the better for ANY IR 3d Scanner on the market!
It all depends how much IR light the material absorbs. E.g. some black fabric isn’t black in IR spectrum and is ( resp. the pattern projected on it) very visible to scanner’s camera . From my experience rubberized, black surface can be scanned better than black, glossy surface like black car paint for example.
This rubber material e.g. wasn’t much of an issue but applying additional scanning spray which leaves no residue after “evaporation” or similar (e.g. dryshampoo, footspray, 70%Isoporopyl alcohol + non-nano zinc powder,…) - which often easily can be wiped of or brushed of - probably would give an even more clean surface.
There is often some dust on the everyday parts that act as scanning spray! So , dusty black surface I wouldn’t clean before scanning it if you can’t apply anything on top of it .
In my car Miraco (and pop3 would ,too) could pick all the black surfaces in that area, but you see, it isn’t the cleanest space atm, which helped 
The question is what you want to do with the scan afterwards? For direct 3d print the cleaner the scan the better. For reverse engineering a bit noiser scan might not be a problem.
As said , avoiding additional IR light from the sun helps the IR 3d scanners no matter the manufacturer. There are scanning modes on revopoint’s IR 3d scanners which crank up the brightness of (to our eyes invisible) projected pattern like “dark mode” which helps with dark/black and shiny/glossy materials. Also the shorter the scanning distance, the better as it results in more visible scanning pattern. This all is the case here with those pedals.
