LG has developed a firmware update that pretty much completely fixes flashing and blocking issues experienced with 2018 LG OLED models
Sony 2018 OLED TVs in particular seem to have the same sort of problems. In fact, I saw the issues for myself recently on a 65A9F - and having pointed them out to Sony, the brand has now acknowledged to me that there is indeed an issue. It is currently working on a solution.
There are reports of similar but significantly less aggressive issues on some Philips (Europe) OLED TVs, too.

Sony's A9F OLED TVs will not, it seems, be getting a firmware update to resolve reported raised black level and noise issues.
Here’s Sony’s response in full:
“Following our own tests, we found that some content will have raised black levels, of which have [sic] quite low level signals which are sensitive to dark shadow gradation and low level signal handling.
However, current Sony TV models feature a powerful processor and smooth dark gradation, so the TV represents dark shadow with less annoying artifacts on the display.
Moreover, for FY19 OLED models, our engineering team have improved factory calibration, which is more accurate for smoother dark shadow gradation, so we expect to see less noise. And we advise consumers to be aware of panel calibration which helps to maintain dark shadow performance. Details can be found on the Sony website https://www.sony.fr/electronics/support ... s/00173463."
Sony suggests that its A9G TVs will suffer less with the noise and flashing issues thanks to improved factory calibration.
But then the statement also suggests that having your Sony OLED TV professionally calibrated may improve things. And that for its upcoming A9G/AG9/A8G/AG8 OLED models, Sony’s engineers have reduced noise and improved near-black gradation by improving their own OLED panel factory calibration techniques. This implies that the issues are not just to do with the sources after all.
