Pine script Security function differ in return values when called with syminfo.tickerid and Security symbol directly - security

Question

could someone help me with this clarification:
EMA9 calculated using security function, one with syminfo.tickerid and the other one with Security symbol differ in the value returned. Shouldn't they be same? Below is the snippet of code.. Any help is highly appreciated..
Thanks.
//EMA9 calculation function
get_Close_EMA9_Stats()=>(close - ta.ema(close,9)) *100 / close
//EMA9 function called using security function passing syminfo.tickerid and security symbol----
request.security(*syminfo.tickerid*, "W",get_Close_EMA9_Stats() , lookahead = barmerge.lookahead_on) //Case1
request.security(*"NSE:APOLLOHOSP"*, "W",get_Close_EMA9_Stats() , lookahead = barmerge.lookahead_on) //Case2
//VALUES from Case 1 and 2 DIFFER..SHOULDN'T THEY BE SAME WHEN THE SAME TICKER BEING USED BUT ONE HAVING SYMINFO.TICKERID AND THE OTHER SECURITY SYMBOL DIRECTLY IN THE SECURITY FUNCTION

When I try on my end, both request.security() calls yield the same result.
Maybe the symbol you have on your chart differs from NSE:APOLLOSHOP ?
You can check the value of syminfo.tickerid by adding this code at the end of your script.
if barstate.islastconfirmedhistory
var lbl = label.new(na, na, syminfo.tickerid, color=chart.bg_color, textcolor=chart.fg_color)
label.set_xy(lbl, bar_index, high)
