Certain chemicals will be.
Since you have oil in DPF, question is how much of byproduct of oil burn (sulfated ash and phosphorus-SAPS) is going to stay there after regeneration or some will go out? That is impossible to find out. SAPS is what eventually kills DPF/GPF. That is why vehicles equipped with it use so called Low-SAPS oils. It is to prolong life of DPF/GPF but eventually SAPS will clog it. Regeneration cannot burn carbon build up created by SAPS. So, only way to find out is to start car, keep driving and hope for the best.
