Highlighting unique distinct values in a range using conditional formatting

Repeated values are not highlighted, only unique distinct values.

Conditional formatting formula:

=IF(ROW(A1)>MIN(ROW(tbl)), COUNTIF(OFFSET(tbl, 0, 0, MIN(ROW(A1)-MIN(ROW(tbl))), MAX(COLUMN(tbl))), A1)+COUNTIF(OFFSET(tbl, MIN(ROW(A1)-MIN(ROW(tbl))), 0, 1, MIN(COLUMN(A1))), A1), COUNTIF(OFFSET(tbl, 0, 0, 1, MIN(COLUMN(A1))), A1))

Named ranges

tbl (A1:D4)
