Jack never mind. No need to convince me or you. You like your 7D II and that's OK. Others just have different preferences. Maybe you may consider checking out Raw Digger and have a closer look at Canon files and Sony RAW files. I am sure you will find some files on the net, if not I will be happy to help you out.
To start with, here are 4 Jpegs. The RAWs where underexposed, and then pushed by 4 stops. The Canon 5DMKIII image is unusable, due to noise. This kind of noise can not be removed with LR. The A7r is very clean. If there is some noise left, it might be removed with LR.
Now you can write in Red, Blue, Bold of even Kanji to emphasis your point in endless threads. But that doesn't change the facts. It just makes it harder to read. If you are into nature photography, specialized on spiders, or butterflies etc, which you will usually photograph with a low DR background that shouldn't bother you.
The nice insect pictures you make, can be done with an A6000, and A77II a D810 or with a 7DII. The sensors requirements are relatively low. The right lens might be much more important there. Fact is, that beside the usability you like, the 7DII has the weakest sensor of all of those, as has been explained by others who know much better than me, extensively.
Over and Out.
