Android TV Release Time frame?

You said “posters”. Posters do not appear in preplay screens in the old interface. I just checked and posters are:

The only original image asset used on the pre-play screen is the background image, and that is still there [old / new]. So nothing has been removed here. I do think they need to tone down the ultrablur on it, though.

Your complaint is the same if they added the logos to the legacy interface – they might have not made a toggle there, either. Again, you’re conflating a single change (Logos) with the entire app rewrite.
