Sentinel-2 L2A: Sun angle & terrain corrections

Sentinel-2 L2A includes an atmospheric correction to get the Surface Reflectance but I guess it does not correct the sun angle ?

I am currently working on icebergs (of size 300x300m) images and I wondered if I should apply a sun angle correction to get more consistency between the shots of the different days.
Does it make sense to correct only the sun angle, without making terrain correction (since no DEM is available for the icebergs) ?
