The correct rating here is -191, 0, 191 [...] and is derived analytically

In general there is no such thing like an (absolutely) "correct rating". The mapping between winning percentage (or probability) and rating difference depends on the underlying rating model, and there is more than one model, and not all three programs you are comparing use the same model AFAIK.

Furthermore, as HGM has shown, also the number of draws has an influence on the ratings. In addition to that, BayesElo (I don't know about Ordo here) also accounts for the colors. I don't know whether the (roughly) 55% win rate for White was considered in your example since you didn't mention it.
