Does using non OEM pads specifically (not just non dealer labor) create more war

[mathanery]

I want to narrow down something specific after going back and forth on this warranty question for a while now, my 911 is still under warranty and needs pads replaced, and I've been mainly focused on whether going to an independent shop instead of the dealer creates risk, but I realized I haven't actually separated two different variables here, is the warranty concern more about who performs the labor, or is it actually more about whether the parts themselves are genuine OEM versus quality aftermarket, because those feel like two separate risks that I've been lumping together without really distinguishing between them, does anyone know if a certified independent specialist using genuine OEM pads carries meaningfully less warranty risk compared to that same specialist using a well regarded aftermarket brand instead, or does warranty language typically not care about that distinction as long as the installation itself is done properly and documented, I've been trying to book Porsche brake pad replacement with certified specialists in Dubai and some of them offer both OEM and aftermarket options at different price points, which is honestly what made me start questioning whether the part origin matters just as much as who's doing the actual work, has anyone specifically had a warranty situation come up where the aftermarket part itself was the issue being questioned rather than just the location of service, or does that distinction rarely actually come up in practice regardless of what a lot of people online seem to worry about, also if aftermarket parts do carry more risk, is that risk specifically isolated to brake related warranty claims, or could using aftermarket pads theoretically be used to question unrelated claims elsewhere in the car, which honestly seems like a stretch but I want to understand if that's a realistic concern or not, I'd like to actually understand this distinction properly before deciding whether to go OEM or aftermarket through an independent specialist, so if anyone has real experience or knowledge specifically about part origin mattering versus just service location, I'd appreciate hearing that clarified.
