Power BI矩阵特定行条件格式设置技术求助

I need to format rows in a Power BI matrix to match a specific style: the row labeled "Total Net Income" should be highlighted in light green, while all other rows remain white. I've researched and tested various approaches but haven't achieved the desired result. Below is the DAX measure I've written that comes closest to my requirement, but it still doesn't work correctly. Can someone help me fix this?

CF Rows = 

IF  (HASONEVALUE('D Headers_Blob'[Detail])
    ,IF( FIRSTNONBLANK('D Headers_Blob'[Detail] , 1) = "Total Net Income"
        ,"lightgreen"
        ,"white"
    )
    ,BLANK()
)
