Yes and much much more since UK & SQ are best buds!
If you’re a KF EG/PPS - an additional 10kg luggage allowance (I assume it would be on top of the 2x23kgs), mileage credit to KF, access to Vistara’s lounge in DEL - I don’t think they serve booze there and would prefer the SQ lounge anyways (not open 24/7 though).
While those are KF elite benefits you might get them anyways since you’re flying SQ J on the same day even on separate tickets. You should ask for those benefits and of course let us know how it goes.
