As a person who works in the film industry with a husband who is hard of hearing, I have definitely had my share of frustrations when it comes to subtitles. On my previous TV, when the subtitles would appear on screen, the rest of the image would dim as compensation for the white of the subtitles and then brighten again when the subtitles disappeared (which I assume is the reason you ask about local dimming.) Thankfully, this TV does not have the same problem. There is an "Off" setting in the auto local dimming menu, which is why I am not sure the Sony rep said it can't be turned off, but IMO, the High setting produces the best image. There are some bloom issues, but interestingly the bloom is worse on the lower local dimming settings than on the high setting. (it seems that Sony has tried to do a "smoothing out" of local dimming in medium and low where the zones next to the bright zone gradually decrease in brightness all the way to the edge, which ends up creating edge blooming and the horrible "Light Bar Crawl" for things like rolling credits. But the bloom is much lower in the High setting, and for my preference, the added black levels and contrast with the High setting outweigh the small amount of bloom which is really only noticeable on letterboxed films where the subtitles are below the image on absolute black. One more observation is that DOLBY VISION content does seem to default to it's own local dimming settings (maybe this is what the sony rep was talking about when they said it can't be turned off) and DOLBY VISION -Dark does create an obnoxious flicker and edge blooming in some darkly lit scenes, but the DOLBY VISION -Bright does not have this problem.
