I can imagine that this might also be the reason why Windows shows a full-screen popup when you switch to and from a high-contrast theme: to hide glitchy applications during the transition period.

In that respect the situation is similar to before this change, other than it being less likely to occur (and perhaps never or rarely in practice).

Yes, I think having inconsistent transient states is not an acceptable trade-off, that's why I think reducing them by 99,9% (from guaranteed to happen, to almost hever happening) is sensible. If it does happen anyway, it shouldn't crash your application but show up as a visual glitch (I mean, we're talking about colors). In that sense, you can "rely" on it.
