Hmm,
Somewhat surprised  the 28mm didn't behave just a bit better.  Exit pupil 
distance to sensor may affect this.  Sensor stack in 6D is 2mm but not sure 
about "optical thickness."  See Roger's article-- "Sensor Stack Thickness: When 
Does It Matter?"

Summary article below which you probably already read too , but just in case.

Wide Zuiko's on A7RII reported behave much better than A7r, but still have 
modest issues--subtle though.  Kolari mod on A7RII is as good as it gets but 
than to to have custom profile for native lenses as color is mucked up some.
Besides that, the native lenses to behave well with very minimal degradation of 
resolution but modifying an expensive cam like that gives me pause.  Ironically 
 OMZ wide's may behave very nicely on aps-c Nex with Speedbooster as the optic 
corrects for  sensor stack thickness.   Oh, some have used Cornerfix with very  
good results to make things easier--even fixed some color smearing with RF 
lenses in earlier days.  Perhaps you might like that solution.  RF lenses are 
always  the most problematic of course.
