Is there any reason LG doesn't produce a G4 42 inch?

Like, is there any technical limitations with MLA/MLA+ that LG cannot produce 42 inch 4k G4s?

I am pretty sure there were some leaks about what display types (32 inch 240hz 4k and etcs) LG plans to produce in the upcoming years. Is there anything similar to it for 42 inch screens?
