HDCP 2.1? I haven't seen that. I don't recall the minimum version required for 1080p (HD) video. 1.1, maybe? I suppose that it wasn't nice of them to make 2.0 and 2.1 not forwards compatible with 2.2. I wonder whether 2.2 will have the same issue with 2.3? (Not that I have any 2.3 devices.)
There is an LG player that is supposed to support M-Disc BDXL. It's the WH14NS40.AVAU10B. It's cheaper than the WH16NS60. It apparently needs a nonstandard firmware to do 4k stuff, though.
I don't know what the longevity of a burned BDXL (not M-Disc) is. I hope that it's more than a year. I wonder whether consumer drives will be available in 50 years? I guess the grandkids could take the discs to a service. The old shoebox full of photo prints had its advantages. I think that the modern technique is to put everything into the cloud. (Might not be a good idea for Anthony Weiner.)
I recall being surprised a about 12 years ago when a co-worker ordered an old recording from Deutsche Gramophone. It was obviously a burned CD. I guess that they were doing burn-on-demand discs at the time. I haven't contacted him since tof discover whether it had any longevity issues.
