That just seems like you reboot_to_payload.bin file is not Hekate. Vanilla Atmosphere certainly doesn't give you that nor does certain packages that don't bundle Hekate (which is becoming more common due to DZ).
No I don't think it was, it was whatever comes with vanilla Atmosphere as it comes with reboot_to_payload.bin,
I'm guessing it requires a USB connection for the payload which I didn't have attached, hence the black screen.
