Dont worry too much .
You will have reduced your head stability slightly . Each time you move beer and fob it some of the protein chains that make the foam anre broken down .
There is the potential to introduce spoilage bacteria and oxygen by dropping beer from a height into another container.
Best to exclude air by sending it down a pipe to the bottom of the bucket.
The live, still active yeast will absorb and use some of the oxygen you will have introduced. Introoducing or exposing finished beer to alot of air can produce cardboard flavours. Or all manner of bacteria ,although the low ph ( should be 3.9 – 4.0 ) will kill off alot of them , as will the ABV.
