IDK if Marlin is polling the AD converters or uses interrupts? If it's polling, then maybe the AD-conversion is still ongoing while Marlin polls the value?
Interrupt handling routines are also tricky, especially with a constant data stream from Arduino to OctoPi.

I'm sure the LCD values are filtered or averaged. Otherwise we would only see dancing pixels. Might be, that the data sent to octoprint are raw sensor values without bandwidth filtering or averaging.
The capacitors on Ramps might be too small or mislabelled crap. We've seen that in the past too often..
