AFAIK, the embedded thumbnail is only used (at least, I'm not familiar with K 4 iOS/Android/PC/OSX) on the Touch/PW in Cover View mode, and even then, in some very specific cases only:

* On the Touch (with JBPatch): When the ASIN (exth 113) is unset or invalid (an UUID).
* On the PW: When the ASIN (exth 113) is unset.

Otherwise, the firmware falls back to the sideloaded thumbnail (or downloads it from Amazon if the ASIN is valid).

(And, yeah, 240x240 seems to be the 'standard', at least that's what both KG & Calibre do. Fun detail: It's actually a tiny bit too small for the PW screen, making those easy to spot).
