Thank you.I posted the feedback. FB22575333

Thanks for the clarification. On my iPhone 15 Pro (A17 Pro), MTLFXTemporalDenoisedScalerDescriptor.supportsMetal4FX(device) actually returns true. In other words, because supportsMetal4FX(device) returns true on iPhone 15 Pro, I have no way to avoid taking the Metal 4 FX code path.
