Hey, that amazes me a lot. I bought the scale 8 years ago for CHF 52. Now the same product is suddenly much more expensive... :-(
Regarding your question: The variant with the strawberry heart kitsch symbol seems to be the same. Its control buttons + display do not differ from the original (black) version.
The pure white version seems to have a different display. The kg numbers in the photos look much more angular - in the original, the corners of the numbers of the weight indication are displayed much "rounder".
Whether this has also changed other "inner values" (e.g. accuracy etc.), I cannot judge. Perhaps there are simply several hardware/firmware versions which only differ in detail.
If you want to know for sure, you should ask the manufacturer or Digitec.
