You are using an R7 with a diffraction limited aperture of f/5.2, @Maximilian is using an R6ii with a dla of f/9.6. The RF 100-400 has an aperture of f/8. The two cameras respond differently when a 1.4x TC is put on the lens. The R7 is pushed further into dla-limitations but the R6ii less so. It's a waste of time if not disadvantageous putting TCs on to narrow lenses on the R7 but you can squeeze out more resolution with FF cameras. I know this from direct experience with my R7 and R5ii bodies as well as from theory.It shows a 100-400 element, which I don't like (i use 100-400 with TC 1.4) and the details are blurry...
Unfortunately you can't get more out of it ... let's face it, the 100-400 with TC is not the sharpest lens (Don't take this as a criticism, I've been using that lens for a long time and I'm bothered by the fact that it's not very sharp and detailed, I always have to additionally sharpen the RAW photos in software)
