code pattern to test if list has all the same

all() stops at first occurance of False but min() have to go through all list elements. So it can be said that all() is faster.

If performance is a consideration then generator comprehension could be a choice:

if all(isinstance(x, float) for x in foo):
List will not be created, instead values are returned one at the time and at first False code stops.
