I do not understand the ! and ++ in {! arr[$0]++; next}
Replace by {arr[$1]; next}. Not storing a value in the array saves sone memory! $1 strips spaces, can make sense if there is invisible trailing space (and embedded spaces wouldn't work anyway when later comparing with $1). The next jumps to the next cycle, no need for checking the FILENAME again. {print $0} is a default action if there is just a condition.
Code:
awk ' FILENAME=="reference.txt" {arr[$1]; next}  # create an array without values 
        !($1 in arr)' reference.txt inputfile > outputfile
