Sony 100-400 GM - Vignetting issues normal ?

Hi - i recently acquired a 100-400 GM lens and am finding it difficult to use when editing images. I get two types of vignetting which are difficult to compensate for in post: standard dark corners and when stopped down to f11 i am getting both dark corners and a white ring which become more pronounced as soon as any contrast is added in lightroom:

Adding a bunch of dehaze really exaggerates the issue:

Is this to be expected with this lens or is there a possible issue with it?
