Yep, that's it. It seems to be the only way to rip a 4K. No drives (that I know of) allow ripping 4K "out of the box"!

I think you're correct; as far as I know ripping 4K/UHD with no modification to the drive and/or drive firmware is not possible without other workarounds, which apparently are possible, as I elaborate on below. Apparently as of recently at [CCC 37C3: Unlocked] (December 2023) Adam Batori demonstrated a side channel attack against Intel SGX and AACSv2 in his talk called "Full AACSess: Exposing and exploiting AACSv2 UHD DRM for your viewing pleasure" although that has nothing to do with the specific drive used to my knowledge, though the specific Intel CPU used may have quirks which may make their particular implementation CPU and/or CPU microcode and/or motherboard dependent.
