RF 28-70mm soft left edge or normal performance?

I would like to hear comments form someone owning R5 and RF28-70mm about left edge performance of my lens. Following full resolution image is taken at 28mm, f2. How does this compare to you lens?

28mm, f2, Focus Center of the image, left edge seems much worse than right.

Here is also 28mm, f4 version. Soft left edge might be easier to spot on this one.

28mm, f4, Focus Center of the image, left edge seems much worse than right.

Did also some close distance testing inside. Left is also here pretty bad compared to right side. Siemens stars are crops from the extreme corners. Focused camera center of the lens and took picture (ibis off) and set lens to manual focus. Moved camera on tripod head (without moving tripod) so that I could set Siemens star in the each corner and took picture and combined all in this image.

Test setup 5 images from tripod, focus center.

Some more picture can be seen on: https://mve.kuvat.fi/kuvat/Testikuvia/

Site might be slow outside Finland.
