I did play them side by side and found the sound to be the same, D, but maybe I’ll make a closer comparison. I will be interested to hear about your Pianino when you get it. By “playable” sellers often just mean that sound is emitted when they blow into it and press keys down. Unless it has been worked on, it will need new gasket material and maybe some tweaking of a spring or two and of key pad alignment. But what I discovered was that these are fairly easy fixes.
