Can't play 3D Blu-rays after 4.74 update

I would greatly appreciate it if anyone with 4.74 can confirm/deny this.

After updating to Firmware 4.74, I'm unable to play US 3D Blu-rays. Some BRs play only a 2D image, and some don't even start only giving a warning message, "This disc has recognized that your player and/or display does not support 3D playback or your firmware requires updating..."

Starting one disc, I also got the notice that I can view 3D in my PSVR; would I like to (I checked 'No', because my TV does a better job). In diagnosing this, I removed the PSVR HDMI loop, and just connected the PS4 straight to the TV — still with issues.

My setup has been working flawlessly prior to this update.
