HTC One m9 installation

I’d like to install /e/ on my HTC One m9. I’ve assumed I could use the installation for HTC One m8 since the 2 devices are almost the same.
Am I completely wrong here?

SoC looks different to me → Compare HTC One M9 vs. HTC One (M8) -
m8/m9: Qualcomm MSM8974AB Snapdragon 801 vs MSM8994 Snapdragon 810 (20 nm)

I think you’d need a custom build for the m9, the xda sort
