Logitech is building their own switches for at least a couple generations now. I don't think they would be "rebranded generics".
I'll be waiting for the reviews, though.

they look like https://kono.store/products/kailh-choc-mx-switches with standard cherry stems so you can use any keycaps
Perhaps they’re rebranded generics, can’t say.
