So, according to AnalogHD monochrome will suck, or at least be sub par to my plasma
I wouldn't say "suck".
I'm far from a black and white enthusiast, but I've watched a few of the top movies such as The Phantom Carriage (a must-see among the others), Metropolis, Nosferatu, Citizen Kane, The Seventh Seal, and Le Dernier Combat (yeah, I know, not a "real" one; don't laugh, I was curious) on my 65C9.
In none of them was the dark-gray banding an issue or even visible. It's more that it can
be visible in black and white movies, not that it often is. To be honest, the celluloid film used in old movies produces way more banding than OLED at their worst (that infamous Arrival scene).
Still, the benefits of OLED (as compared to CRT and Plasma - versus LCD there's no contest!) for black and white are limited. Among emissive displays, OLED TVs are blindingly bright, enough to watch most movies in daylight... but I can't imagine watching a black and white film in anything but total darkness. The color of the real world is a total immersion breaker. And in the dark, you won't be using the OLED's entire range of brightness.
LCD (LED, QLED) TVs are completely unfit for your purposes.
Black and white movies are dominated by black. Not all scans and not all edits will bring that black to true zero, especially for pre-1920 movies, but many will. I mostly watch Criterion releases (like I said, I'm not a dedicated enthusiast - my understanding is they only do the top 1% most popular movies) and they do. When you don't have a lot of colors, the quality of black becomes really important. What little light a black and white movie offers looks that much better when it's set against a perfect black background.
In color movies it's just the dark scenes where the black levels matter. In black and white it's almost everything. And since almost none of these movies are 16:9, you'll always have vertical or horizontal bars, so it's really everything.
