Solving playback issues

Has anyone verified that the 4850 works properly on a Samsung S90C?

I did file with BBB as a last resort because Roku will not help me on my 4802 (still in warranty), Roku immediately responded with a cut-and-paste response that they'd contact me immediately, and then ghosted both me and the BBB complaint.

I mean, that's just super disappointing.

In my BBB complaint I stated I'd be happy to try a 4850 if sent to me and if it worked, I'd be satisfied and if not I wanted a refund.  If Roku ever responds to my rejection of their "response", I should probably just insist on a refund.

Right now the BBB case is just sitting there.  If this doesn't resolve soon, I'm going to go back to Amazon (place of purchase) and see if they will refund me since Roku is not standing behind their warranty.

Just to add another data point, I had a 4660 connected via a Denon AVR to a Samsung KS8000.  Never had an HDCP error in 5 years.  I now have a 4802 and an LG C3 connected via the same Denon AVR.  I get HDCP errors sporadically, most often on HDR shows but occasionally on an SDR show.  I get the errors regardless of whether frame rate matching is on or off.  I get the HDCP error screen for a few seconds but the audio continues uninterrupted.  The HDCP errors are random and inconsistent.  I recently got 3 in a 45 minute Dolby Vision show on Apple TV.  Then for the next 2 nights, I got none on another Dolby Vision show on Apple TV.  I don't think I've ever had an HDCP error on Netflix but I only have the HD tier so I don't see HDR or DV shows on Netflix.  At this point, it's not annoying enough to make me switch to another device.
