I'm still on Octane Blender Version 3.07. So maybe it is a Problem with newer Versions or just some setting problems in Photoshop...
I don't know if v3 will work with my RTX GPUS but v4 does. Unfortunately on v4 it is the same.

I've found the reason of such behaviour. The Blender's gamma was set to .04545 and display device was set to sRGB.
Setting back to None and gamma 1 brought back the correct alpha on renders.
