For your viewing pleasure I cut up my second oil filter yesterday, a Fram Ultra XG7317. I left it in the clamp to drain overnight and I looks waaaay better than the XG9688 I took off my Hyundai GDI recently. Of note I did compare the resistance of the bypass value springs and the 9688 had a noticably lighter feel despite being a 9-15 psi vs. 13 psi on the 7317. Using the skills I acquired obtaining my BS Degree in Advanced Bypass Value Engineering from BITOG University I presume to assess that the bypass valve in the 9688 saw some usage while the 7317 retained a firm feel indicating little to no usage. For some people I know it is difficult to believe that the filter media is the path of least resistance inside a spin on can oil filter unless or until media saturation occurs, especially in a Subaru when the antiquated OEM oil filter uses that dread 23.2psi bypass spec from 2009.
