…orCheck` `ComponentRef.setInput` internally calls `markDirtyIfOnPush` which only marks the given view as dirty but does not mark parents dirty like `ChangeDetectorRef.markForCheck` would. https://github.com/angular/angular/blob/f071224720f8affb97fd32fb5aeaa13155b13693/packages/core/src/render3/instructions/shared.ts#L1018-L1024 `markDirtyIfOnPush` has an assumption that it’s being called from the parent’s template. That is, we don’t need to mark dirty to the root, because we’ve already traversed down to it. The function used to only be called during template execution for input bindings but was added to `setInput` later. It's not a good fit because it means that if you are responding to events such as an emit from an `Observable` and call `setInput`, the view of your `ComponentRef` won't necessarily get checked when change detection runs next. If this lives inside some `OnPush` component tree that's not already dirty, it only gets refreshed if you also call `ChangeDetectorRef.markForCheck` in the host component (because it will be "shielded" be a non-dirty parent).

markDirtyIfOnPushhas an assumption that it’s being called from the parent’s template. That is, we don’t need to mark dirty to the root, because we’ve already traversed down to it. The function used to only be called during template execution for input bindings but was added tosetInputlater. It's not a good fit because it means that if you are responding to events such as an emit from anObservableand callsetInput, the view of yourComponentRefwon't necessarily get checked when change detection runs next. If this lives inside someOnPushcomponent tree that's not already dirty, it only gets refreshed if you also callChangeDetectorRef.markForCheckin the host component (because it will be "shielded" be a non-dirty parent).
