Is there a time difference between receiving price data with excel and receiving price data with ...

...EIKON api?

We are checking Korean stock prices with a 20 minute delay on EIKON Monitor. 
So whether I get the closing price with TR.CLOSEPIRCE in the Refinitiv Eikon tab in Excel or the TR.CLOSEPRICE using get_data in the Eikon api, are all the prices delayed by 20 minutes? 
Or is the Eikon api showing a price with a delay of more than 20 minutes? 
I am wondering if it is the same time delay whether receiving price data with EXCEL or Eikon api. 
The reason for asking this question is that when I received TR.CLOSEPRICE from the Refinitiv Eikon tab in EXCEL at around 4:20 pm today (for example, '005930.KS'), the price on March 2 came out correctly. However, when using EIKON API's TR.CLOSEPRICE, the price came out on February 26th. And after about 5 minutes, the price came out on March 2. 
Therefore, please inquire if there is a time difference between the price data received by EXCEL and the price data received by EIKON API. 
Thank you very much for your hard work.
