Is LG Uplus not very good? The device subsidy benefits seem to be the best

According to Ajungdang,
based on the iPhone 17 Pro:
KT is 740,000 KRW / 2-year contract with the 11 plan for 6 months
LG Uplus is 400,000 KRW / 2-year contract with the 11 plan for 6 months
Is it really a carrier that is this unpopular?
