I don't like it but it's what it is.
Thanks for the info. I've only noticed it a few times while owning this TV (mostly episodes of The Orville, which is a bit like a modern Star Trek: The Next Generation). While not ideal, given that it's only happened a few times, I don't mind watching affected scenes at a Local Dimming setting of Low and then turning it back up to Medium. I really haven't noticed it in the vast majority of content.
Re the black bars, it's going to depend a bit on settings and environment (whether you have a bias light, etc.). It's true they're lighter than OLED in some situations (others, honestly, I can't tell much of a difference), but I'm more than happy with their performance. In HDR you are going to see some lightening of them if really bright objects are right next to them. But it's completely acceptable and actually quite good in everything I've watched so far (to be fair, though, I've watched more SDR and full-screen HDR than HDR with black bars so far since owning it, although I have watched a bit of the latter with no complaints). For me (and I'm only speaking personally), mentality comes into play too. I've found just accepting the possibility of them getting lighter if bright spots are next to them, thinking about it similarly to ambient light extending the picture like some bias light systems do, has made it easier for me to not worry about them. It's similar to how if you go OLED, you have to accept risk of burn-in and that some blacks are likely crushed. There's no perfect display yet, and trying to find one leads to a lot more frustration than figuring out what minor limitations you can live with and accept and going with the best TV that doesn't have any major ones. For me, that was the Z9F, and I'm happy with my choice. (If that still doesn't ease your mind, looking up footage of old rear-projection televisions also helps =oP. ^.^).
