2019 Porsche Macan — fuel trims are positive at idle and improve with RPM

2019 Porsche Macan S, about 50,500 miles. Long-term fuel trims are much more positive at idle than at 2,500 RPM. No obvious misfire. Does that pattern still make an intake/vacuum leak the first place to look? I am in Los Angeles.
