Basically there are just few brief shots - maybe five or six through the whole movie - apart the animation, which is all open matte; they are the same seen in Vouka’s screenshots:
At least it’s interesting to see that color grading is different - it’s the only difference I spotted so far, apart ep.8 BD/Novy Kanal.
I searched on youtube for that animation clip, and I’ve found a couple of clips, really bad quality, that were indeed full screen 1.33:1; I wonder where they are from, as the source could be used to phase out the logo completely…
