Strato V flickering/strobing with HDR

I’ve started to have an issue with a flickering/strobing with HDR movies on my Strato V. This seems to occur immediately after a scene changes particularly when there are bright portions of the image. We were watching Hidden Figures last night and it was unwatchable and we had to download the HD version. I have a ripped copy and no issue playing on Apple TV via Infuse. Video components are Denon A10H, JVC NZ7, Lumagen. I was having a similar issue watching a couple other recently downloaded HDR movies (Leon the Professional and Apollo 13). I’ve had this setup for a year without issue and haven’t changed anything but haven’t watch these particular movies before on K. I did try a reboot of the Strato V but no change. Any ideas? I saw another thread with a flickering issue but that seems to be with DV and a Valerion projector that is fixed with KOS 26. So seems unrelated. I don’t have the new software yet.
 
I still can’t figure this out. I swapped HDMI cables to a certified 8K cable. I verified 2 other sources of the same movie from a UHD rip (Ugoos and Apple TV) without issue. Also the second output of my AVR goes to our living room system for watching K there and on our LG OLED no issue so it seems to be the Strato V in combination with the Lumagen and NZ7. I also tried a DV movie, Tron Ares, with the same issue. I’ve had no issue for a year with the same system. Should I try a factory reset of the Strato V? I guess next step is contacting K support.
 
K support says OS 26 should fix this issue and they pushed it to my Strato V. I won't be home till the evening to test. Still confused why it would have just happened though. The last software update was in January. Fingers crossed it's fixed.
