Saw the caps on TrekCore so I watched 'Where Silence Has Lease' this afternoon, hard to get this one wrong because the Enterprise is darkly lit for the majority of the episode. The probe launch and CGI replacement model I can forgive, even the very noticeable matte lines, but the model element used for the Yamato was completely wrong.
The new one just looked ridiculous from an angle because its a head on shot of the ship.
Its an element that has already been found and re-composited in Season 1 here
, its just been flipped for the Yamato. Really stuck out like a sore thumb to me.
Take a look at the Viewscreen shots as well, the colour bleed from the blue screen is dire.
